JACKSONVILLE, Fla. -- Someone knocked a Jacksonville man unconscious and carved the words "Wife Beater" into his stomach, according to the Jacksonville Sheriff's Office.

A police report states the 22-year-old naval officer was attacked after he left a Southside nightclub.

The man told police he went out to Bourbon Street Station to get a drink, but said that he decided to leave the club after he saw one his wife's friends.

The last thing he said he remembered was walking to his car while checking his cell phone. When the man woke up in a haze, he lifted his bloody shirt and found the phrase carved into his stomach.

"Obviously, someone walked behind, hit him with something with enough force to knock him out. He fell to the ground, they lifted his shirt and took a box cutter or some type of blade and inscribed the words 'wife beater' in there," said JSO spokesman Ken Jefferson. "This is very bizarre. You don't hear of anything happening like this. He has been branded by somebody."

The man, who was arrested in March on a domestic battery charge, filed a police complaint Monday on the advice of his naval commander.

Detectives continue to investigate the case.
