Police say a former boxing champion has been shot to death during a robbery in Atlanta.

Atlanta Police Sgt. Warren Pickard says 41-year-old O'Neil Bell was gunned down Wednesday morning. Pickard says Bell and another person were shot while getting off a bus before two suspects robbed them. Bell was pronounced dead at the scene in southwest Atlanta.

Bell had held four different titles during his 13-year boxing career, including the WBA, WBC, and IBF cruiserweight titles. In his last match, Bell beat Rico Cason with a technical knockout in the first round in 2011. Bell finished his boxing career with a 27-4-1 record.

Pickard says the second victim, who wasn't identified, was shot in the hip and was taken to a hospital. Police say the investigation is still ongoing.
