Los Angeles Mayor Eric Garcetti and Police Chief Charlie Beck are calling for calm and patience as three investigations are underway into the police killing of a homeless man Sunday. Police say the man "forcibly grabbed" an officer's gun before he was shot to death.

Beck called the incident a tragedy that followed a "brutal, brutal fight."

The police confrontation with a man known as Afrika was filmed by at least two eyewitnesses. A dramatic video sparked criticism of the police, as it showed several officers attempting to hold him down before shots rang out.
