An arrest report alleges boxer Floyd Mayweather Jr. threatened and hit his ex-girlfriend in an argument that led to a felony charge that he stole her cellphone last week.
Mayweather's 10-year-old son told police he witnessed his father hitting and kicking 30-year-old Josie Harris during the argument at Harris's home in southwest Las Vegas.
The 33-year-old Mayweather hasn't been charged with domestic battery or assault.
He turned himself in to police on Friday and was freed from jail on $3,000 US bail after being booked on a grand larceny charge over the missing cellphone.
He's due in court Nov. 9.
Mayweather's lawyer, Richard Wright, wasn't available Monday. On Friday, he denied wrongdoing on Mayweather's behalf.
The undefeated Mayweather could potentially be jeopardizing his chances for a superfight with Manny Pacquiao, whom he berated in a controversial internet video post last week, along with his boxing career.
