An Anne Arundel County Maryland cop in Baltimore to celebrate Cinco de Mayo on Tuesday bit another man's testicles during a brawl over a woman, authorities said Wednesday.

Michael Flaig, 30, was charged with assault after the fight Tuesday night in the alley behind Looney's Pub in Baltimore's South Linwood neighborhood.

According to the charging documents, Flaig had been fondling a woman when her friend and roommate, the alleged assault victim, intervened.

The alleged assault victim left on foot not long after but heard footsteps behind him. When he turned, he saw a fist coming at his face, according to court papers.

But the victim managed to dodge the punch, bring Flaig to the ground, and then straddle him, the court papers read.

Flaig struggled to escape while a second man, who police have yet to identify or arrest, punched the victim.

Unable to break free, Flaig allegedly bit the victim in the crotch and ran off.

"The bitee actually got the better of him in the fist fight. After we broke them up is when he disclosed he'd been bitten in the testicles," witness Thomas Bourne told NBC affiliate WBAL.

"He was upset, took him a long time to calm down. He indicated he needed medical assistance. He was bleeding in his area after what happened," Bourne said.

A woman approached responding officers with a description of Flaig, who had simply gone to another bar on the block.

The officers observed "Flaig had blood shot eyes, slurred words and a strong odor of (alcohol) coming from his person," according to court papers.

Flaig's police powers were suspended and he has been placed on paid administrative duty, according to Anne Arundel County Police.
