Five Georgia officers have been fired after a 60-year-old man died by suicide while alone in a police interview room, the department said.

William Harvey had been taken to Savannah police headquarters on April 3 for questioning in an aggravated assault investigation, the Savannah Police Department said.

Officers left the interview room and returned to find Harvey unconscious, with injuries to his neck made by his shoelaces, according to the Georgia Bureau of Investigation, whose agents were brought in to investigate. The GBI ruled Harvey's death a suicide.

A Savannah police spokeswoman said there was no video footage while Harvey was alone in the room.
