Los Angeles police officers shot and killed a homeless skid-row robbery suspect who grabbed at an officer's gun during a scuffle as they tried to subdue him in a confrontation captured on video, police said on Monday.

The man, known by the street name Africa, had been living for weeks in a tent outside the Union Rescue Mission building where Sunday's shooting occurred and had a history of violent, erratic behavior, the mission's director said.

Footage of the shooting, widely circulated on the Internet, marked the latest in a string of incidents that have put police across the country under heightened scrutiny over the use of lethal force, especially against minorities, the disadvantaged and the mentally ill.
