KENOSHA, Wis. (CBS 58) -- The Kenosha City Council President could face criminal charges after an altercation last week.

Alderman Anthony Kennedy had a restraining order filed against him after a fight with a coworker.

Arthur Bish, who works with Kennedy at Metro Yellow Taxi in Waukegan, says Kennedy attacked him.

"He went crazy at the Metro Taxi office," Bish said. "He hit me with a chair."

Kennedy addressed the incident at Monday's council meeting.

"I am deeply embarrassed by my actions," he said. "I violated my own personal code of conduct."

Bish applied for a stalking no contact order against Kennedy, and a judge granted it.

"He just lost control, but it's not the first time he's lost control," Bish said.

Kennedy asked people Monday not to rush to judgement.

"I do not apologize for defending myself," he said. "I do not apologize for preventing further harm to myself or others.”

Kennedy says he hasn't been fired from the taxi company. No one we spoke to there could confirm that.

Kennedy will have a hearing in Illinois court next month.

Bish says he's considering filing criminal charges.
