Yip Kai-foon, a notorious Hong Kong gangster known for holding up jewellery stores in the 1980s with an AK-47, has died in a public hospital, aged 55.
One legislator remembered the violent criminal as a committed advocate of prisoners' rights, and a "loving and optimistic man".
Formerly Hong Kong's most wanted man, Yip was serving a 36-year stint in the maximum-security Stanley Prison for possession of firearms and escaping custody in 1989.
He had been in custody since 1996, when he was rearrested after a shoot-out in Kennedy Town, during which he was shot in the spine, leaving him wheelchair-bound.
Yip publicly expressed remorse for his crimes in 2010, the South China Morning Post reported.
