The family of Mohamed Bah, a man shot by police in Harlem last year, gathered near City Hall on Monday to call on the Manhattan district attorney to further investigate the incident.
Police say they responded to a call on September 25 about an emotionally disturbed man in his apartment, when Bah lunged at officers with a knife.
They fired stun guns and rubber bullets, but when that did not stop him, they fired live ammunition, hitting him nine times.
Relatives said Bah's mother was simply trying to get medical help for her son.
"If it was a self defense I could understand one bullet. But nine bullets were lodged in his body, 10 were fired. Four police officers present at the scene and one person only," said Souleymane Bah, Mohamed's brother. "Where is the offense or aggression over here? Who committed aggression? Who committed violence here?"
The Manhattan district attorney said the case is under investigation.
