Larsen was sentenced to eight years in prison in 1989 for the murder of tradesman Erik Dam, who was stabbed to death on an S-train at Rødovre station. Following his release from prison, Larsen joined the Bandidos during the Nordic Biker War in 1996. He rebelled against the club's leadership after the murder of Claus Bork Hansen, an expelled Bandido and close friend of Larsen who was shot and killed by Bandidos members in Vanløse in March 2001. Larsen was subsequently killed by a car bomb in the parking lot of the chapel at Glostrup County Hospital in September 2003. In 2005, two senior Bandidos members were sentenced to life imprisonment for the bombing, which in 2006 was reduced to sixteen years in prison.
