Joseph Matz, of Arlington, is accused by police of unarmed bank robbery and several other crimes.

A suspect in a Wednesday unarmed robbery of a Sovereign Bank was arrested and charged at 12:21 p.m. — then charged again hours later for apparently giving police a false identity.

Joseph Matz, 40, of 12 Russell St., Arlington, was also a handful in another way, police said: After the 10:59 a.m. robbery at 515 Massachusetts Ave., in Central Square, he took officers on a foot chase, ultimately losing them while dodging through back yards.

While police set up a perimeter and called in State Police dogs, Matz broke into a house at 74 Norfolk St. and climbed to its roof, police said. When he was spotted there, officers called in the Fire Department to put up ladders and the Cambridge Police Department Crisis Negotiation team to talk him down.

He resisted at first during talks through a second-floor apartment window, then came down and was arrested and charged with unarmed robbery, breaking and entering, resisting arrest and disorderly conduct. He told them he was James D. Harrel, police said, with the rest of his information — his age and address — correct.

His fingerprints betrayed him, though, and he was charged again as Matz.

He has an outstanding warrant out of Cambridge for threat to commit a crime, as well as numerous federal and state convictions, police said in a 4:02 p.m. e-mail.
