Police are investigating an afternoon attack that injured a man at the Lighthouse Plaza in Atlantic City.

Craig Davison, 56, was struck in the head with a hard object causing a laceration, a female friend told police who responded to the 12:54 p.m. call Sunday, Sgt. Monica McMenamin said.

Witnesses said Davison was in his 15th-floor apartment with three females and the suspect, when the man suddenly grabbed Davison’s wallet from a table and fled out the door, according to the report. Davison chased him into the stairwell, where he was assaulted.

Police found Davison on a stairwell between the 11th and 12th floors of the building on the 300 block of Atlantic Avenue.

The suspect is described as a black male with a medium complexion last seen wearing a white T-shirt, black basketball shorts and a New York Yankees baseball cap.

Davison was treated at AtlantiCare Regional Medical Center's City Campus.
