Some are alleged to have accepted bribes in exchange for giving protection to brothels and gambling dens Thirteen Kowloon policemen have been arrested over corruption allegations, including accusations that some took bribes to protect brothels and gambling dens. A source said that some of the officers were arrested in their stations while they were on duty. Others were picked up at their homes in the operation involving 300 officers from the Independent Commission Against Corruption (ICAC), backed by police, on Monday night. Two senior inspectors, a station sergeant, three sergeants and seven constables were arrested in what was one of the biggest anti-graft raids on the force in recent years. Sixty-three other people were arrested. 'One of the allegations claimed that some of the arrested officers had received bribes from the operators of gambling dens and vice establishments for tip-offs prior to raids,' the source said. 'It is also alleged that some of the officers accepted advantages from the operators of restaurants to prevent harassment from triad members.' Last night, the ICAC confirmed that it had arrested 15 women and 33 men - including the 13 officers - for suspected corruption and involvement in illegal activities linked to graft. Twenty-eight other people were arrested for gambling offences. 'It was alleged that the arrested officers were suspected to have accepted advantages for offering protection to entertainment establishments, restaurants, illegal gambling and vice establishments,' the statement said. The operation, codenamed 'Le Chang', arose from corruption complaints and a months-long investigation, according to an ICAC spokeswoman. 'It's our investigation but police offered us assistance to raid some locations like gambling dens, vice establishments and entertainment premises,' she said. The civilians arrested over the graft allegations comprised 10 operators and staff members of discos and karaoke venues, eight operators of brothels and illegal gambling stalls, two masseuses, two operators of pornographic websites and three of their assistants, and 10 mainlanders - eight women and two men. Police arrested another 28 people - 23 men and five women - for playing pai kau (Chinese dominoes) and seized about $7,000 table money in an alleged gambling den in the wholesale fruit market at Yau Ma Tei during the joint operation. Officers from the Police Tactical Unit sealed off the exits of the market before plainclothes officers from the police and ICAC moved in. Officers also visited a number of entertainment establishments in Yau Ma Tei and Tsim Sha Tsui, including the Club 348 disco in Nathan Road, during the operation. Another source said officers from the police force's Internal Investigation Bureau had been alerted so that police could offer assistance to the ICAC during raids on the fruit market, and other gambling dens and vice and entertainment premises in Yau Ma Tei and Tsim Sha Tsui. An official police spokesman said they would not comment on the ICAC operation. Last night, the 76 arrested people, aged between 20 and 71, were still being held for questioning by police and ICAC officers.
