A third St. Marys teen is facing charges tonight after police say he robbed another minor on Thursday.

According to court records, the 16-year-old boy was arraigned late Friday afternoon.

He’s charged with robbery, burglary, and conspiracy to commit robbery, and had bail set at $250,000.

Earlier Friday, two 17-year old boys were charged after police say all three confronted a juvenile at gunpoint inside a S. St. Marys Street home while wearing masks.
