Stephen Tse

Stephen Tse (Tse Chun-on or Chun-wah, aka "Sky Dragon") is the former restaurateur and head of the Ping On syndicate, which controlled criminal activity in the area of Boston Chinatown from the late 1970s through the mid-1980s. Tse was jailed for sixteen months starting in 1984 for refusing to answer questions after being subpoenaed by the President's Commission on Organized Crime, marking the start of the decline of Ping On influence over Boston.

After his release from contempt charges relating to the subpoena, Tse and the Ping On were forced to share power with rival groups that had grown stronger while he was jailed. A failed 1988 assassination attempt on two competing leaders who had openly defied him led to his eventual arrest, extradition, and conviction in 1996.
