LAS VEGAS (AP) — Police sought boxer Floyd Mayweather Jr. for questioning Thursday about a domestic battery complaint lodged by an ex-girlfriend who recanted a similar claim in 2005, police and his lawyer said.

“She alleges he hit her. We’re looking for him to get his side of the story,” said Officer Barbara Morgan, a Las Vega police spokeswoman. “We’re looking to talk to him as a potential suspect.”

No warrant was issued, and no charges were immediately filed.

Mayweather, 33, is undefeated as a professional fighter. He goes by the nickname “Money” and is considered one of the sport’s top performers.

Mayweather has been arrested before on battery and assault allegations.

He was acquitted by a Nevada jury in July 2005 after being accused of hitting and kicking Josie Harris during an argument outside a Las Vegas nightclub.

At trial, Harris, the 25-year-old mother of three of Mayweather’s children, testified she had lied to police because she was angry Mayweather left her for another woman.

Harris filed the complaint currently being investigated by police.

Attorney Richard Wright, who represented Mayweather in the 2005 case, told The Associated Press on Thursday that he was talking with police about the new case, but Mayweather had not surrendered for questioning.

“We’re addressing it with law enforcement,” Wright said. “We will cooperate with them professionally and as required by law.”

Mayweather wasn’t at a southwest Las Vegas house when officers responded to the domestic violence complaint a little after 5 a.m. Thursday, Morgan said.

Harris was later taken to a hospital for treatment of injuries that police Officer Bill Cassell said weren’t described as serious.

Mayweather has a record of 41-0 with 25 knockouts. He earned more than $20 million in May from his fight in Las Vegas against “Sugar” Shane Mosley.
