LAS VEGAS (AP)—Boxer Floyd Mayweather Jr. has been arrested in Las Vegas on a felony theft charge stemming from a domestic violence complaint by his ex-girlfriend.

Mayweather, 33, was booked Friday on a grand larceny charge at the Clark County jail and held on $3,000 bail, Las Vegas police Officer Bill Cassell said.

Mayweather’s lawyer, Richard Wright, said Mayweather is accused of taking an iPhone from Josie Harris, his ex-girlfriend and mother of three of his children.

“He surrendered,” Wright said, denying the allegations against Mayweather.

“He did not commit any grand larceny,” Wright told The Associated Press. “Josie can’t find her iPhone. We’re attempting to find it or replace it. We’ll cooperate in the investigation. We expect to get the matter resolved.”

Harris made a police complaint and sought a Family Court protection order Thursday alleging Mayweather pulled her hair, punched her in the head and twisted her arm while she screamed for their children, ranging in age from 7 to almost 11, to call 911.

Police said Thursday that Harris was treated at a Las Vegas hospital for minor injuries.

“Please order Floyd Mayweather to not try and contact me,” Harris wrote in an application for a protection order that said the couple separated in May after living together for seven years.

“Floyd has threatened to have other people do harm to me as well and if (there) is a way I can be protected from that please help me,” the document says.
