A tip caller told State Police at Reading that Algis Diaz, 24, who is suspected in several Berks County bank robberies, was inside the Berkshire Mall Saturday afternoon.
The caller also identified the suspect's car, which was reported stolen from the State College, Pa. region, and police staked it out in the parking lot.
When Diaz came out of the mall, he ran off when police tried to apprehend him.
A Wyomissing Police K-9 unit was on the scene. The officer released the dog and yelled for the other officers to stop their pursuit.
One Pa. State Trooper, Robert Hess, apparently did not hear that the dog was released and was bitten on the right leg when he didn't stop pursuit. He was treated at Reading Hospital.
Meanwhile, as Diaz ran back into the mall, T-Mobile sales rep Rueben Rivera heard the commotion and tackled the suspect.
"There wasn't really much of a struggle with him because he looked like he was running out of breath when he was running, so when I tackled him onto the floor, it was pretty much easy," Rivera said.
Police took Diaz into custody and he faces charges of: Receiving Stolen Property, Aggravated Assault, and Recklessly Endangering Another Person.
Both State College PD and State Police Fogelsville also hold warrants for Diaz for Theft and Receiving stolen Property.
Diaz will face more charges. He's locked up in the Berks County prison.
