Off Duty Thwarts Robbery

Bad timing on the offender's part:

• A Chicago Police officer who was off duty interrupted an armed robbery of a Near West Side gas station last night – foiling it and catching the culprit, police said.
  
  Donald Davis, 23, of the 7600 block of South Morgan Street, was charged with attempting to disarm a peace officer and attempted armed robbery, police said.
  
  
• As the officer was trying to place him into custody, Davis tried to disarm the officer and escape but the officer was able to keep control of the weapon and detain Davis with the help of the staffer, the report said.

Sounds like Donald could have used a little extra "ventilation."

Regardless, nice job Officer.
