Tan Chor Jin (Chinese: 陈楚仁; pinyin: Chén Chǔrén; 29 March 1966 – 9 January 2009), also known by his alias Tony Kia, was a Singaporean gang leader known for fatally shooting 41-year-old Lim Hock Soon, his former friend and nightclub owner, using a semi-automatic Beretta 0.22 calibre pistol on 15 February 2006. Tan, who had underworld affiliations and was a member of Ang Soon Tong since his early years, had also robbed the Lim family of their valuables before he escaped Singapore to Malaysia, where he was arrested ten days later. The media gave him the name "One-eyed Dragon" given that he was blind in the right eye.
