A 16-year-old is being charged as an adult in connection with an armed robbery during a Facebook Marketplace sale.
Allegheny County Police say they responded to the 700 block of Hays Avenue in Mt. Oliver Monday afternoon.
The victim told them they planned to sell a custom-built PC from a Facebook Marketplace transaction.
Instead, three people showed up, allegedly displayed a gun and stole the computer.
Detectives later saw five people nearby, matching both the description of the robbery under investigation and a previous armed robbery.
The group ran, but officers eventually caught up with 16-year-old James Beasley.
Detectives recovered the computer and other items from his home.
He is charged with robbery and illegal possession of a gun by a minor.
