A 17-year-old boy from Lebanon has been charged as an adult for allegedly robbing a man with the 27-year-old victim's own gun, city police said Friday.

Police said Anthony Beck committed the crime around 11 p.m. Sunday in the 300 block of North Fifth Street. They said Beck and an unknown man took money from the victim and then Beck and the victim went riding in the victim's car.

During that ride, Beck pulled a pistol from the car's glove compartment, pointed it at the victim and demanded more money, investigators said. Beck fled after the victim told him he had no more cash, they said.

Beck was arrested Wednesday at his home on charges of robbery and simple assault and sent to county prison in lieu of $100,000 bail. Police said the stolen gun wasn't recovered.
