Tucson police said Sunday that a tip led to the arrest of Robert Francis Krebs after authorities circulated surveillance photos of him entering the Pyramid Credit Union and at a teller's window. They say Krebs had a handgun, demanded money from the teller and was given cash before running out of the bank.
Police released the photos after Friday's robbery. A local hotel clerk called police Saturday to report a man that looked like the one in the photos had tried to cash a check.
Police began checking nearby hotels and located Krebs. He was booked into jail on two counts of armed robbery.
It's unclear if he has an attorney.
