Police did not find weapon when they patted Young down, but a “concerned citizen” told police that Young had thrown an object behind a house before officers arrived, the report said.

Officers checked the area and found a loaded silver revolver, the report said.

Young was arrested without incident, police said. He faces charges for illegal firearm possession and threats.
