The suspect is described as a tall, slender man with brown hair, grey on the sides, with a beard. He's in his 50's and was last seen wearing a light green sweat shirt.
As a precaution, nearby area businesses and schools were put in lockdown while they searched for the suspect.
The susepct was last seen running west on Irving off of Greenwood.
No weapons were seen during the bank robbery.
This will be the city's sixth unsolved bank holdup in two years. But police don't believe the more slender robber is the serial bank robber who held up several local banks -- because that suspect was shorter and much heavier.
