HOUSTON -

Police have arrested three burglars who tripped a security alarm in a pharmacy in north Houston.

Investigators say the thieves pried open the front door of a vacant business next to that pharmacy on Greens Road near the North freeway.

Officers say they broke a hole in the wall and snuck into the pharmacy. That's when one of the crooks tripped the alarm, notifying Houston police to the scene.

Police arrested one burglar at the pharmacy and K-9 units were brought in to track down the other two.
