Police are looking to speak with boxer Floyd Mayweather Jr., who is a suspect in a domestic violence case involving the mother of his child, Josie Harris, TMZ reports. Sources tell the gossip site that Harris called the police at 5:03 a.m., claiming that Mayweather had attacked her. She was taken to Las Vegas' Southern Hills Hospital. Police have not been able to get a hold of Mayweather, and are seeking to speak with him to determine if they should arrest him. This is the second time Harris has accused the boxer of domestic violence: In 2003, she alleged that he attacked her in her car. In 2005 she admitted that she lied to cops out of anger after Mayweather broke up with her to be with another woman.
