Tucson police shot and killed a suspected bank robber on the city's south side on Thursday afternoon.

The officer-involved shooting occurred about 1:30 p.m. outside the Wells Fargo branch at 145 E. 22nd St., between South Sixth and South Fourth Avenues.

Sgt. Chris Widmer, a police spokesman, said police received an alarm call from the bank. Contact was made with someone inside the bank who told authorities that a robbery was in progress.

Officers arrived and confronted the suspected robber outside the bank and shots were fired, Widmer said. The man, who had a gun, was  shot.

Police officers performed CPR on the man but he was pronounced dead at the scene. No officers were injured.

22nd Street has been reopened to traffic, but Fourth Avenue from 21st to 22nd streets will remain closed for several more hours, police said just before 7 p.m.
