MOUNT PENN, Pa. -

A man accused of attacking and robbing an elderly woman as she got off a bus in Mount Penn will be spending time behind bars.

William Smith was sentenced Tuesday to 9.5 to 20 years in prison after pleading guilty to robbery charges.

Back in August authorities say Smith pushed an 85 year-old woman after she got off a BARTA bus on Perkiomen Avenue and took her purse.

The woman suffered an injury to her face and a broken arm.
