NORRISTOWN, Pa. (CBS) — Police in Montgomery County are looking for a man who has allegedly assaulted and robbed multiple women in Norristown.

Norristown Police say the attacks happened in numerous locations between Dec. 1 and Dec. 8:

• December 1 at approximately 4 AM at Airy and Haws
• December 1 at approximately 7 AM at Stanbridge and Haws
• December 2 at approximately 7 AM in the 500 block of Haws
• December 2 at approximately 745 PM at Fornance and W Marshall
• December 8 at approximately 630 PM in the 700 block of Noble Street

Five women told police they were grabbed from behind. Some of the women reported being robbed.

“I usually come out here at night to get my brother from work so I’ll probably be a little bit more alert when I come out. I did not know that was happening right now,” said one resident.

Other residents said they’re reconsidering how they get around now.

“I walk out to the corner store to get the paper or if I need bread or something. Now I’m not sure if I want to go walking anymore,” another resident said.

The suspect is described as a black male, around 6 feet tall, with a light to medium complexion, a medium to heavy build and may have some facial hair. He was wearing a dark-colored hoodie and either jeans or sweatpants.

The victims told officers they didn’t know the suspect and police are asking residents to remain vigilant.

Though none of the women were seriously injured police are concerned his behavior may escalate if he is not caught.

“We want the public to make sure they’re paying attention to their surroundings if they see anything that looks suspicious that they’re calling us that they’re doing the best that they can to be in pairs when it’s appropriate to be out in pairs,” police said.
