Tucson police are looking for a man who has robbed the same restaurant three times this month.

The man robbed Viva Burrito, 1372 W. St. Mary's Road, Dec. 3, 21 and 23, according to a Tucson Police Department news release.

The robber is described as 17 to 19 years old with a thin build. He was last seen wearing a gray sweat shirt, gray bandanna and dark pants.

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