Police in Shanghai have detained 10 suspects in the fatal clash between two gangs that left two dead on Friday, local authorities said Saturday.

An argument over debt dispute between two gangs became violent and shots were fired Friday noon at the entrance of Huilihuayuan Residence on Changshou Road, Putuo District, police said.

A seriously-wounded man died Friday after he fled the scene, while another one died in Huadong Hospital early Saturday. Two others were injured and being treated in the hospital, police said.

Police have detained 10 suspects, including the two injured, seized four self-made guns, a knife and two vehicles.

The police would give no further details.

Chinese law prohibits the private ownership of guns. The last time Shanghai witnessed a shooting on the street was in July 2002, when one gang fired shots at another, injuring two people.
