Alleged leaders of two Sun Yee On triad factions are among 10 gangsters being hunted by Hong Kong police after a spiral of attacks and revenge attacks between the two gangs in the past month, sources told the Post on Wednesday. One of them was the Tsim Sha Tsui faction leader known as “Sai B”, sources said. A Hongkonger in his late 30s, he is understood to have taken the reins of the gang after its leader Lee Tai-lung, 41, was chopped to death outside the Kowloon Shangri-La in 2009. “The other leader wanted by police in connection with the revenge attacks is the Kwun Tong faction leader, alias Man Sun Chung,” one source said. Police insiders said initial investigation indicated the two leaders fled to mainland China and police have sought help from mainland counterparts. The spat between two factions of the powerful triad organisation began after a dispute at a birthday party in a pub on Hanoi Street, Tsim Sha Tsui, on March 30.

By Wednesday the man, 33, badly wounded, was still in hospital, in a stable condition. It was understood the Tsim Sha Tsui gang made two attempts at revenge earlier this month. In mid-April, police arrested four alleged members of the Kwun Tong faction over the chopping. They were granted bail pending further investigation.
