LOWER MERION, Pa. (CBS) – Lower Merion officials are calling for a full investigation after a young woman went public at Wednesday night’s commissioners’ meeting, accusing a township cop of sexually assaulting her last October and then stalking her for more than a month.

Eyewitness News is not naming the 26-year-old woman from Bryn Mawr.

“I know I’m not the first, and I know I’m not the last.”

According to sources, the woman initially considered the officer her friend.

The friendship, sources say, started last summer, but ended last October. Sources say that’s when the woman claims the officer pursued her romantically and at one point, groped her without her permission.

“I was stalked outside my window, he saw me naked and I have post traumatic stress because of this.”

Liz Rogan, Board of Commissioners President, said, “I had no idea anyone was going to come in and speak about that matter and I felt awful for the woman when she spoke to us.”

Eyewitness News learned from sources the woman never made a formal complaint. Sources say she was afraid to do so. But when a concerned neighbor notified township officials, the woman claims a fellow police officer detained her for no reason in a parking lot near her home last October.

“I just want justice. I’m not seeking money. I just don’t want this to happen to another girl.”

Township officials say the investigation will be handled by the Montgomery County District Attorney’s office.

“That is a very serious allegation and it’s something that’s appropriate to be referred to law enforcement and so when it comes to us we’ll certainly be looking at it,” D.A. Risa Vetri Ferman said.

According to sources, the accused officer is in his 40s and married with children.
