So this is how Eminem is celebrating his semi-retirement.

Police in Detroit said Monday they are seeking the hip-hop superstar for questioning for his alleged role in a strip club beatdown last week.

Eminem and his entourage were hanging at the Cheetah Club, a nudie bar located on Eight Mile Road, into the early hours of Thursday when a fight went down at approximately 1:15 a.m. The rapper, whose real name is Marshall Mathers III, was using the toilet when an unidentified man in the restroom began chatting him up, per local ABC affiliate WXYZ-TV.

One of Eminem's bodyguards warned the man not to talk to his boss. At that point, another patron in the restroom, identified only as Miad J., told the guard to go easy on the fan.

"He kept on going and I said, 'The guy's not saying nothing, he's just talking to him, he's not saying anything,' " Miad J. told WXYZ.

According to an account in the Detroit Free Press, Eminem's bodyguard then shoved Miad J. The 48-year-old man says he tried leave, and that's when the rapper allegedly started "swinging."

"Eminem got done and boom," Miad J. said. "I wasn't even expecting it. I was just minding my own business, taking a leak."

The entertainer and his crew fled the club following the incident. Eyewitnesses quoted in the Free Press said that another member of the posse, described a longtime Eminem friend and protégé named Trick Trick, flashed a gun outside the club, but did not aim it at anyone.

A manager at the club confirmed that a scuffle had broken out involving Emimem but declined to discuss specifics. A spokesman for the Detroit Police Department said that authorities have launched a probe and are hoping to get Eminem's side of the story. No word yet whether any charges will be filed.

The Grammy winner's publicist at Interscope Records, Dennis Dennehy, could not be reached for comment.

This isn't the first time the performer's been sought by Detroit's Finest.

In 2000, Eminem was arrested on a pair of gun-related charges. One involved a heated dispute with an associate of rap collective Insane Clown Posse. The other came when the real Slim Shady used an unloaded 9mm to threaten and pistol-whipping a man at a bar for allegedly kissing then wife Kim Mathers.

After cutting a deal with prosecutors that saw him plead guilty to a lesser charge, he escaped with a $10,000 fine and two years' probation, which he completed in 2003. Both experiences inspired the tracks "Soldier" and "The Kiss."

After remarrying his high school sweetheart last January, Eminem filed for divorce without explanation from Kim just three months later and the two are currently seeking joint custody of their 10-year-old daughter, Hailie Jade.

While he is taking time off from his own recording, Eminem has been keeping himself busy in the studio producing pal Obie Trice's sophomore album, Second Round's on Me, due out next month. He also recently agreed to star in a big-screen update of the classic TV western Have Gun Will Travel.
