Two men wearing ball caps passed demand notes and held up two banks on the same street in Squirrel Hill within hours of each other on Friday.

Sgt. Aaron Beatty of the city robbery squad said that while police were still processing one robbery, the other happened right across the street.

But it was all a coincidence.

"There's no connection," he said.

In the first holdup, a man walked into the National City bank at 1730 Murray Ave. at 1:16 p.m. and passed a demand note. He didn't show a weapon and got away.

While the robbery squad was there, another man walked into the Citizens Bank at 1807 Murray and passed a note at 3:43 p.m., this one saying he had a gun and a bomb. He didn't show a weapon, either, and also got away.

Police said they believe the first robber is the same man who held up the Parkvale Bank on Murray Avenue last Tuesday.

He's white, between 5-feet-7 and 5-feet-9, and appears to be in his mid-30s. He was wearing a green baseball cap, a blue jacket and jeans and black sneakers.

The second robber is white, about 6-feet-3 and 250 pounds, 40 to 50 years old, and was wearing glasses, a baseball cap and a big puffy coat.

No one was injured in either robbery.

Good photos of the second suspect taken by a bank security camera are available at www.bankguys.us, a Web site that publishes information about fugitive bank robbers.

Sgt. Beatty said the robbery squad has responded to incidents in the past where two banks in the city have been hit at about the same time, but he couldn't recall two unrelated heists happening on the same street in the same afternoon.

Anyone with information is asked to call police at 412-323-7152.
