A Manchester Township woman was assaulted and robbed in the driveway of her home Saturday.

Northern York County Regional Police said the 37-year-old woman was getting out of her car at her home in the 600 block of Hayley Road about 7:05 p.m. when she dropped her purse.

As she was picking it up, a person came up behind her, hit her head and grabbed her purse, which contained cash and prescription medication, before fleeing the area, police said.

The woman told police that she isn't sure if an object or the person's hand struck her.

She received a large swollen bump on her forehead as the result of the attack. She refused medical treatment, police said.

The woman was not able to provide a description of the attacker, police said.
