A 50-year-old police officer fatally shot a man who attempted to rob him late Sunday night in a parking lot, authorities said.

The officer's name has not been released. The man who was shot was identified as 21-year-old Juvon Allen.

According to a Little Rock police incident report, the officer told investigators he was loading a bike onto the back of an SUV in the Vantage Point apartments parking lot at 2300 Rebsamen Park Road about 11:30 p.m. when Allen came up behind him and placed a gun to the back of his head.

The officer turned and swung at Allen, and Allen "hit him in the mouth" before the officer pulled his "off duty weapon" and opened fire, the report said. Allen fled but turned back a short time later and fired toward the officer, hitting a parked vehicle, the report said.

Police were notified a short time later that Allen had been taken to St. Vincent Infirmary Medical Center with gunshot wounds in his upper chest, left-side middle rib area and lower rib area. He died at the hospital.
