COVINA, Calif. — Police say a man with a knife tried to rob a Southern California pizza restaurant just a few hours after burglars had already stolen from it, and he was stopped by an officer there because of the first crime.

Covina police Lt. Trevor Gaumer tells the San Gabriel Valley Tribune that burglars broke into Pizza Chalet Tuesday and made off with $1,500. As the owner was cleaning up after the burglary less than three hours later, the knife-wielding man walked in and demanded money.

The owner flagged down an officer providing extra patrol help.

Gaumer says the suspect, 19-year-old Ernest Ramirez, didn’t listen to the officer’s order to give himself up, and fought with arriving officers briefly until he was subdued.

Gaumer says Ramirez was treated for minor injuries.
