Butler police are seeking an unknown robber who snatched an Apple iPhone from a man late Saturday night.

The suspect, police said, is described as a black man, about 5 feet, 10 inches tall with a thin build. He was wearing a white T-shirt and dark blue jeans or black pants.

The victim, a 24-year-old Butler man, told police that he passed the suspect while walking on West New Castle Street near North Chestnut Street. He said the robber grabbed him from behind and ripped the iPhone and a set of earphones from him, according to a police report.

The suspect, after taking the property, valued at $500, fled but immediately returned and demanded the other man’s wallet.

The victim refused and the suspect took off. No injuries were reported.

A pair of witnesses on the porch of a nearby home, meanwhile, told police that they saw the crime and the robber’s getaway.

Officers searched the area but could not find him.

Anyone with information about the suspect is asked to call police at 724-287-7743.
