Scottsdale police have arrested a gunman suspected of trying to rob a smoke shop.
Officers say Maurice Williams went into Quality Tobacco Sunday near Thomas and Scottsdale Roads and demanded money at gunpoint.
When he didn't get any cash, detectives say Williams went to a nearby smoke shop where he tried to hide.
When police got there, he fled, but they were able to catch up to him and take him into custody.
Authorities found Williams' gun on the roof of a building. He is facing armed robbery charges.
