The ICAC’s Major Setback: The Rise and Fall of the Carrian Group

On 20 September 1996, at Hong Kong’s High Court, George Tan, former chairman of the Carrian Group, pleaded guilty to two counts of conspiracy to defraud.

The name George Tan may sound unfamiliar today. In the 1980s, however, he was famous. The Carrian Group he founded was a multinational finance and property conglomerate with three listed companies and more than 200 subsidiaries at its peak.

Behind that glamorous image was a vast fraud. According to the Independent Commission Against Corruption (ICAC), between 1980 and 1983 Tan used deception to obtain US$238 million in loans from Bumiputra Malaysia Finance (BMF).

He was sentenced to three years in prison one week after his plea. By then, nearly eleven years had passed since his arrest and fourteen years since the collapse of his business empire. Why did the investigation take so long? How could an agency famous for dismantling corruption in the police force move so slowly? The Carrian case lets us examine how a corruption case moves from investigation to trial, and why even a powerful anti-corruption agency can suffer a major defeat.

The ICAC’s three functions

Under the 1974 Independent Commission Against Corruption Ordinance, the ICAC has three functions: investigation, prevention and community education. They are carried out by three departments.

1. Operations Department investigates cases. Its teams cover the public sector and the private sector. Most of the ICAC’s roughly 1,400 staff work here.
2. Corruption Prevention Department reviews administrative procedures and recommends changes where they may invite corruption. In 2025 it completed 67 review reports and provided more than 1,500 consultations.
3. Community Relations Department handles public education, media campaigns and community work. It also operates reporting channels. The ICAC’s promise to informants is simple: their identities and reports are kept in confidential files and disclosed only to authorised people who need to know.

A complaint is screened first. Complaints unrelated to corruption are also answered within two working days; where corruption is involved, an officer normally contacts the informant within 48 hours. Once a case enters a formal investigation, external oversight begins.

The ICAC’s investigative powers

The ICAC’s powers include arrest without a warrant when the Commissioner authorises it and there are reasonable grounds for suspicion; detention for up to 48 hours; searches under a warrant, with a narrow emergency exception; applications to restrict a suspect’s travel; written demands for bank and company records; court orders requiring a suspect and spouse to declare assets, expenditure and liabilities; and restraint orders freezing property.

These powers are extensive, but the ICAC cannot decide anyone’s fate. After an investigation it sends the evidence to the Department of Justice, which decides whether to prosecute. Article 63 of the Basic Law places criminal prosecutions under the Secretary for Justice. The separation of investigation and prosecution is meant to prevent a prosecution decision from resting solely on the ICAC’s own judgment.

The Carrian case, which lasted seventeen years, was the ultimate test of that design.

Carrian: from miracle to collapse

Carrian was the longest case in ICAC history, running from 1985 to 2001. Tan arrived in Hong Kong from Singapore in the early 1970s and founded the group in 1977. Within a few years it became one of the city’s most spectacular business stories.

In 1979 Carrian bought 52% of the listed company American International Assurance at HK$6 a share when the market price was about HK$1.50, then used it to list the group. In 1980 it bought the Connaught Centre in Central for HK$998 million and announced a resale for HK$1.68 billion, apparently making almost HK$700 million. The transaction was later found never to have been completed. The paper profit was fiction, but the share price reached HK$17.90 on 5 November 1980.

The money behind the story came largely from BMF, a Hong Kong subsidiary of Malaysia’s state-owned Bank Bumiputra. BMF eventually lent companies controlled by Tan US$292 million for the Connaught Centre acquisition even though one borrower had only HK$2 in registered capital.

In 1982 the property market turned after negotiations over Hong Kong’s future began. Carrian cancelled its cash interim dividend, announced new share issues and then revealed that it could not meet its obligations. Trading was suspended in January 1983 and the group was wound up in October. Its debts reached HK$10.6 billion, including about HK$4.6 billion owed to BMF.

The collapse was followed by a murder. BMF auditor Jalil Ibrahim disappeared after travelling to Hong Kong to examine the books and was found dead in a Tai Po banana plantation on 20 July 1983. Malaysian businessman Mak Fook Hing was convicted of murder and sentenced to life imprisonment. Tan was never charged with that killing; legally, the murder and the fraud remained separate cases.

International cooperation and transfer of jurisdiction

The police initially investigated the Connaught Centre fraud. The ICAC became involved only after a Malaysian inquiry found that BMF had lent about US$800 million to Carrian companies between 1979 and 1983, much of it without adequate security, and that senior BMF officers might have taken bribes. Because the suspected bribery occurred in Hong Kong, the Malaysian committee reported it to the ICAC through the Department of Justice in April 1985.

On 23 May 1985 the ICAC created task force TF3, initially with twelve investigators and eventually more than forty. Evidence stretched across eight countries: accounts in Malaysia, dollar transfers in the United States, bank accounts in Switzerland, and suspects in Britain and France. The Department of Justice assigned six prosecutors, the government hired international accountants and lawyers, and a former BMF general manager became a protected witness. By the end there were four million pages of documents, 450 witnesses and more than 100,000 investigation hours.

On 7 December 1985 British police arrested former BMF chairman Lorrain Osman in London. The ICAC arrested Tan and two former Carrian directors in Hong Kong. Tan faced 43 counts of conspiracy to defraud and unlawful advantages involving more than HK$5 billion, and was granted bail of HK$50 million in cash plus a HK$2 million surety—the highest in Hong Kong at the time.

The trial of the century

The ICAC transferred the Connaught Centre fraud to the Department of Justice for prosecution against six defendants. The trial became known as the “trial of the century”: the prosecution took nineteen months to present its evidence, called 104 witnesses and produced more than 25,000 pages of transcript.

On the 281st sitting day, 15 September 1987, Mr Justice Blair-Kerr ruled that the charges were duplicative and the evidence insufficient. The six defendants were acquitted without being called to give a defence. The government had spent HK$210 million on litigation.

This was a profound setback, but it also exposed the boundary of the ICAC’s power. Once a case reaches court, the court may disregard years of investigative work. Judicial independence is precisely what limits an agency with extraordinary investigative powers.

Ten years of extradition and eventual convictions

The ICAC opened a new investigation into the BMF loan fraud. Osman made ten habeas corpus applications in Britain and spent almost seven years in prison before being extradited in December 1992. He pleaded guilty in 1993 to allowing a US$292 million loan without adequate security and received one year, set off against his British detention.

Senior executive Saminathan was arrested in France but released because French law had no equivalent offence. After a second arrest and years of litigation, he was extradited in February 1994 and sentenced to five years after pleading guilty to two counts of conspiracy to defraud. Former BMF director Hashim voluntarily returned from Britain in 1987; his sentence was increased from four and a half to ten years on appeal. Other bankers were also convicted.

Tan’s own prosecution was finally resolved in 1996. His application to stay the proceedings was rejected, his bail was revoked, and he pleaded guilty to two counts of conspiracy to defraud on 20 September. He received three years and a five-year disqualification from acting as a company director. The ICAC closed the Carrian case in 2001 after seventeen years.

Three safeguards in the ICAC system

The case tested three safeguards. First, the ICAC showed that it could investigate across eight countries, withstand a decade of extradition litigation and turn four million pages into evidence. Second, prosecution remained independent: the ICAC investigated, while the Department of Justice decided whether to charge. Third, the final decision belonged to judges and juries. An agency that investigated, prosecuted and judged would become a monster of power. It might secure more convictions, but it would not retain public trust.

Oversight of the ICAC

After the 1977 police–ICAC conflict and the government’s partial amnesty, an oversight system for the ICAC was established on 1 December 1977.

The system has three layers. Socially representative advisory committees review how corruption reports are handled, corruption-prevention work and community education. The ICAC’s internal L Group investigates misconduct and corruption allegations against ICAC officers, while complaints involving ICAC staff must be reported to the Department of Justice. Finally, the independent Complaints Committee for ICAC Matters reviews non-criminal complaints; its secretariat sits in the Administration Wing rather than the ICAC, and it reports publicly each year.

In 2025 the committee received 17 complaints containing 41 allegations, reviewed 40 and found five substantiated, involving three officers. The point is not the number of disciplinary findings. It is that investigators themselves are watched. The Commissioner answers only to the Chief Executive, but the ICAC’s decisions are scrutinised by prosecutors, judges, juries, advisory committees and the complaints committee.

What the Carrian case teaches

Tan’s case took so long because investigation is only the first stage. Evidence must pass the Department of Justice, the trial court and the appeals process. Each safeguard slows the agency down. In Carrian, the safeguards produced a seventeen-year case, an acquittal in the trial of the century and years of extradition litigation. If efficiency is the only goal, they look like obstacles. If the goal is legitimate judicial authority and lasting public integrity, they are the protections that make power tolerable.

The highest achievement of an investigative agency is not that nobody questions it, but that it can survive losing. Hong Kong lost a trial before the world, yet its anti-corruption system did not collapse because people could distinguish a lost case from a failed institution. The institution endured because it relied on procedures rather than the infallibility of one person or one agency.
