CLEVELAND: Cleveland police say an officer from another department fatally shot a man in an altercation at an apartment complex while working as a private security guard.

Police say the shooting happened Thursday night when the guard responded to a disturbance in a hallway where he found a man and woman fighting. Police say the man aimed a gun and refused to drop it, and the officer fired.

Cleveland police are investigating the shooting. The identity of the 30-year-old man who died at the scene wasn’t immediately released.

The guard works as a police officer in Geneva on the Lake.
