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 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.
