LAS VEGAS - Police said Thursday they were seeking boxer Floyd Mayweather Jr. for questioning about a domestic battery report lodged by a former girlfriend who recanted a similar charge in 2005.
"She alleges he hit her. We're looking for him to get his side of the story," said Officer Barbara Morgan, a Las Vegas Police spokeswoman. "We're looking to talk to him as a potential suspect."
Morgan said no warrant had been immediately filed and no charges had been brought.
Mayweather has faced battery and assault allegations in the past.
In 2005 he was acquitted by a Nevada jury after being accused of hitting and kicking Josie Harris during an argument outside a Las Vegas nightclub.
Harris, the mother of three of Mayweather's children, testified at the trial that she lied to police because she was angry that Mayweather left her for another woman.
Harris is the woman who filed the report currently being investigated by police.
A lawyer for Mayweather said he had been in touch with police and that the fighter would cooperate with authorities.
Morgan said Mayweather, 33, wasn't at a Las Vegas house when officers responded to the report of domestic violence shortly after 5 a.m. on Thursday.
The woman involved alleged that Mayweather hit her during an argument, Morgan said.
Police officer Bill Cassell said the woman was taken to hospital for treatment, but her injuries were not described as serious.
Mayweather, 33, is unbeaten in 41 professional fights.
He earned more than $20 million in May for his Las Vegas victory over Shane Mosley.
However, negotiations for a proposed mega-fight between Mayweather and Filipino pound-for-pound king Manny Pacquiao have repeatedly run aground, and Mayweather provoked criticism last week for a short video posted on the internet in which he denigrated Pacquiao.
