This is one of the upsides to mobile phones:

An astute witness' prompt call to 911 early yesterday morning after seeing some punks breaking into a car resulted in the arrest of three teenagers.

The caller told police that the men had broken out the window of a parked car in the 1200 block of West Geronimo Street, then sped away in a white passenger car.

Leopold Macias, 19, Cody Moon, 19, and a third minor teen were nabbed by Chandler police after a brief chase.

The younger teen was released to his mother pending a criminal complaint, police say.

It's as safe bet that mommy's not too happy.
