Lee Tai-lung Lee, a Sun Yee On boss in Tsim Sha Tsui, was murdered in front of the Kowloon Shangri-La hotel on 4 August 2009 by members of the Wo Shing Wo gang. It was supposedly a revenge attack ordered by Leung Kwok-chung, a senior member of a Wo Shing Wo crew in Tai Kok Tsui who was injured by Lee during a bar fight in July 2006 in Prat Avenue. Following Lee's death, three of his former followers stepped in to defend his lucrative entertainment empire from other triads. In 2011(?), Lee's three followers were tracked by "Ko Tat", another "red pole" in Wan Chai, who failed to spread his influence across the harbour. Tai Hau, leader of another Sun Yee On faction active in Tuen Mun, tried to encroach upon Lee's West Kowloon and Tsim Sha Tsui operations. His attempts were thwarted by an undercover police operation, as a result of which 222 people were arrested in January 2012. The Organised Crime and Triad Bureau suspects that "Ko Chun" may be the latest kingpin of Lee's original turf.
