PONTIAC, Mich. -

Investigators have released the video of a robbery earlier this month at a Radio Shack in Pontiac.

The Oakland County Sheriff’s Office said a man entered the store on North Telegraph Road on Nov. 7 and asked for a phone cable. When a store employee went towards the back of the store, the man pulled out a silver semi-automatic pistol and demanded cash, the Sheriff’s Office said.

The gunman then forced the employee into a back room and stole between 20 and 25 phones.
