MESA, Ariz. -- A woman arrested for causing a scene at a Valley restaurant spat at an officer and on the drive to the police station threatened to hunt down the officer's wife and children, investigators said.

Tammy Ray Barnes, 37, of Gilbert, faces possible charges for aggravated assault and threatening and intimidating an officer.

Police said Barnes harassed customers at the Islands restaurant at 1665 S. Alma School Road on Wednesday and shouted profanities at the manager.

Several arriving officers said when the woman refused to pay her bill, they arrested her on suspicion of trespassing and disorderly conduct.

As Barnes was being led to the patrol car, she spat at one of the officers and struggled with them, officers said. The woman claimed she was a lawyer and kickboxer, according to authorities.

Once inside a patrol car, she began hitting her head against the window and threatening to kill herself, according to police.

She told one of the officers on the drive to the police station, "I will come after you with a vengeance. I will come to your station. I will never let you rest. I will hunt your wife. I will hunt your kids."
