Among the crimes associated with gang activity was a deadly shooting in May 2003 on a busy street, which may have been in retaliation for a driver backing his bus into a rival; in revenge, two buses were set on fire the following year. Fatal stabbings occurred in October 2003 and in 2004. The boyfriend of a bus-company employee was fatally shot in an apparent bus feud in January 2004, and a Chinatown bus operator was shot to death two months later. In a June 2004 incident tied to criminal gangs, two people—a Chinatown bus driver and a bystander—were murdered in a bar in Flushing, Queens; another was shot in the leg. The accused shooter was arrested in Toronto in 2011, and was extradited to the United States. After the 2004 shootings, the New York City Police Department increased its enforcement of Chinatown-bus laws.
