CHICAGO (03/22/2007) -- An off-duty police officer in street clothes was caught on video by a bar surveillance camera beating up a female bartender half his size, authorities said.

Anthony Abbate, a 12-year veteran of the Chicago force, was charged with aggravated battery and placed on leave pending an internal investigation in the attack Feb. 19 as several bystanders watched, department spokeswoman Monique Bond said Wednesday. She said Abbate is expected to be fired.
