Boxing star Floyd Mayweather's legal problems in Las Vegas mounted today when he was charged with two misdemeanor counts of threatening to cause bodily injury to another person, related to an alleged verbal assault against two security guards working in the gated community where he lives.

The charges stem from an alleged incident last Oct. 4, although the security guards opted not to bring legal action immediately after their initial police complaint.

The new charges, filed in Las Vegas Justice Court, are separate from a Nov. 4 incident in which Mayweather also is charged with misdemeanor assault after allegedly poking another security guard in the face with his finger.

In the new case, Aaron Ryan and Miguel Burgos were citing vehicles parked in the street when Mayweather confronted them and allegedly said he had "homies" with guns who could fix the problem, the police warrant stated.

The warrant said the security guards contacted Las Vegas Metro Police the same day but did not wish to have charges brought. Ryan reconsidered later in October.

The security guard in the November incident, working at the same gated community, also was attempting to warn Mayweather about the number of cars parked at the home when he said the fighter verbally berated him and poked him in the face.

Mayweather is scheduled for a Sept. 1 trial in that case. A conviction could carry up to a six-month jail sentence and $1,000 fine.

Far more urgent for Mayweather is a string of felony and misdemeanor charges stemming from a Sept. 9 domestic confrontation in which he allegedly entered the home of Josie Harris without permission, hit and threatened the mother of three of his four children, and stole her cell phone.

A series of delays has pushed the evidentiary hearing in that case to July 29.

A conviction on all charges in that case could carry up to a 34-year prison sentence.
