LAS VEGAS >> Boxer Floyd Mayweather Jr. is facing new misdemeanor harassment charges accusing him of threatening two homeowner association security guards outside his Las Vegas home.

The charges filed Thursday in Las Vegas stem from an October dispute over parking with guards in the gated community where the undefeated prizefighter lives.

Mayweather’s lawyer, Karen Winckler, didn’t immediately respond to messages from The Associated Press seeking comment.

Mayweather already faces a September trial on a misdemeanor battery charge stemming from allegations that he poked a 21-year-old guard in the face during a separate argument over parking tickets in November. He also faces unrelated felony charges in a domestic argument with his ex-girlfriend and two of their children last year.

The new charges allege Mayweather threatened the guards after they cited several of his vehicles parked on the street in violation of association rules.

According to a police report, guard Miguel Burgos told police that Mayweather approached him and co-worker Aaron Ryan after they cited the cars and told them not to touch his vehicles.

The guards tried to explain the association’s parking rules, but Mayweather said he had 29 vehicles and they didn’t need to touch them, Burgos told police.

“I already have a pending gun charge and I don’t want any problems, but my homeboys have guns and I’ll call them to come over and take care of you guys,” Mayweather said, according to Burgos’ account. “What do you guys want to do?”

Mayweather does not have gun charges pending against him.

The guards said Mayweather then took the citations and put them on the windshield of the officers’ vehicle while laughing, repeating the threat several times and telling them to leave.

Police said the guards left and called police, but told officers they didn’t want to press charges. Ryan called police two weeks later saying he wanted to move forward with the case.

Winckler told police in March that Mayweather would not be available for an interview.

Mayweather, 34, is 41-0 in his professional career with 25 knockouts. His last fight was against Shane Mosley a year ago.
