Customer angry over bill shoots two people at Hooters restaurant in Tenn.

KNOXVILLE, Tenn. -- A customer who was upset over his tab fired several shots into a Hooters restaurant, leaving a manager and another patron in critical condition Saturday, police said.

Police were searching for the man, who left on foot just after midnight, Lt. Kenny Miller said.

Managers asked the man to leave after he refused to pay his bill, according to Miller. The man went outside and started firing shots from a .40-caliber handgun at the building, Miller said.

A customer leaving the restaurant and a manager inside were in critical condition Saturday at the University of Tennessee Medical Center.

No other details were immediately available.
