A man robbed a downtown National Bank of Arizona Thursday afternoon, leaving with an undisclosed amount of money.

The robbery occurred at 12:34 p.m., and when police arrived at the bank, 136 N. Stone Ave., the robber was already gone, said Sgt. Chris Widmer, a Tucson Police Department spokesman.

No one was injured during the robbery.

Detectives found out that the man entered the bank and gave a note to a teller, demanding money and threatening harm, Widmer said.

The man received an undisclosed amount of money, and then ran south from the bank, said Widmer.

The robber was described as Hispanic and between 40 to 50 years old. He was about 5 feet 4 inches tall and weighed about 150 pounds.

He was wearing a green trench coat, brown sweater, dark beanie, black gloves and sunglasses, Widmer said.

Anyone with information is asked to call 911 or 88-CRIME.
