Tycoon Albert Yeung and singer Juno Mak are among those released on bail, music awards ICAC officers are probing claims that a record company accepted hundreds of thousands of dollars to terminate the contract of a singer, sources said yesterday. The allegation came as officers from the Independent Commission Against Corruption continued to investigate the alleged bribes-for-awards scam that on Wednesday led to the arrest of 22 people, including tycoon Albert Yeung Sau-shing of the Emperor Group, singer Juno Mak Chun-lung and the president of Universal Music HK, Alex Chan Siu-po. Mr Yeung, Juno and Mr Chan were all released on bail last night. Juno's father Clement Mak Siu-tong, who is chairman of CCT Telecom, and Lee Chun, a director of PCCW's Music Nation, were also released on bail. Meanwhile, singer Joey Yung Cho-yee was seen driving into the ICAC compound in Queensway at about 10pm. Yung sings for the Emperor Entertainment Group. In addition to the bribery claims about the terminated contract, anti-graft officers were still investigating allegations about preferential treatment given to several singers. Sources said those arrested from Universal Music HK and the Emperor Group were alleged to have offered advantages to senior TVB executives to ensure that hits by certain singers would be given favourable positions on the charts and to secure various musical awards given by the broadcaster. But the ICAC did not officially release the names of any of those arrested or the companies involved in its investigation, which is one of the largest probes into alleged impropriety in the Hong Kong entertainment industry. Others arrested in the operation on Wednesday included three TVB staff - assistant controller Ho Lai-tsuen, executive producer Chan Ka-lun and manager Peter Tsang Kwok-keung - and two senior Emperor Group staff, Mani Fok Man-hei and Lisa Kan Chin-chin. The ICAC said no further arrests were made in connection with the investigation yesterday. The senior executives from TVB were still being held for questioning. It is understood that they are likely to be released soon pending further investigation. A further 28 people including four singers and several staff from the TVB production division have been interviewed in connection with the investigation over the past two days. The singers included pop idols Nicholas Tse Ting-fung and Eason Chan Yik-shun. TVB assistant controller Tsang Sing-ming, head of the station's external affairs division, confirmed that it would look into whether it was necessary to review its criteria used to select songs for its music chart and awards following the arrest of its three staff.
