Police said he was arrested on a warrant from Bucks County, on charges of passing a bad check for $5,000 that was used for a deposit on a late-model black Acura TL sedan - the make, model and color of the vehicle driven by the gunman Thursday.
He was taken to police headquarters and questioned by homicide detectives while a search warrant was executed at his residence. Sources said police expected to file murder charges soon.
Police said the suspect was picked up while getting into a white Pontiac rented in New Jersey. He was preparing to leave the area, police said. The Acura was parked nearby and covered with a gray tarp.
The robbery and killings occurred about 8 a.m. Thursday at the Wachovia Bank at Bustleton and Bleigh Avenues, outside the mall. The robber struck while Alullo and Widmaier were servicing an ATM machine, and their driver remained inside the truck.
A bank surveillance photo shows the gunman walking up to the two guards, shooting both of them execution-style, and running off with a bag containing an unknown amount of money. The man then sped off in a black Acura sedan.
Authorities said investigators were led to the suspect by tips received yesterday morning from two people.
The first came from a person who worked for an unidentified auto dealership in Middletown Township, Bucks County. That tipster said a man who had bought a black Acura TL sedan from the dealer - and paid with a bad check - resembled the gunman in the video.
That was followed by a call from a resident of the Woodhaven Road complex, who told police that there was a resident there who looked like the gunman and that there was a black car parked there, covered with a tarpaulin.
Police and FBI agents staked out the building and arrested the man.
