Austin police are looking for the man who committed the city's 15th bank robbery of the year.

Shortly before 3 p.m. Tuesday, a man walked into the Prosperity Bank on West Highway 290 and demanded cash.

He ran out on foot, but police aren't saying how much cash he got away with.

He's described as a black man with a medium complexion. He's about 5'7", 180-pounds and was last seen wearing a white, Gilligan-style hat.

He was wearing a blue long sleeve pull-over with an unknown print in the front of it. He also had on baggy blue jeans and white tennis shoes.
