When York City detectives released a surveillance photo of a robber who shoved a woman to the ground and robbed her of her purse, they hoped the public could help identify him.

What they didn't expect was that one of their own co-workers would help crack the case.

A member of the public who saw the photo recognized the robber as Jason Hollar and called in the tip, according to Detective George Ripley.

"But on top of that, one of our officers went to high school with (Hollar) and recognized him from the photo," Ripley said.

Ripley said Hollar robbed the woman as she stood outside the White Rose Bar & Grill on Aug. 21.

Hollar, 27, of 56 S. Pershing Ave., was arrested about 5:30 a.m. Friday by members of the U.S. Marshals Service fugitive task force at a home in the 100 block of North Newberry Street where he'd been staying, police said.

Sharon Carr, 55, of Manchester Township, suffered scuffed knees and a sore back during the 9:40 p.m. robbery in the parking lot of the 48 N. Beaver St. restaurant.

According to police, Hollar approached her from behind, shoved her to the ground, grabbed her purse and ran.

A White Rose bouncer who saw what happened gave chase and retrieved Carr's purse, but Hollar got away, police said.
