(Story updated on 05/26/2018 at 7:05 p.m. ET with a statement from UFC officials.)

Nick Diaz has been arrested following an alleged domestic violence incident Thursday evening in Las Vegas.

A person within the Las Vegas Metropolitan Police Department identified Nickolas R. Diaz, 34, who is listed in an online in-custody search for the Clark County Detention Center, as UFC fighter Nick Diaz. The person spoke to MMAjunkie on condition of anonymity because the person wasn’t authorized to speak on the matter.

Diaz has been charged with felony domestic battery by strangulation, as well as misdemeanor domestic battery for the alleged incident.

Officer Larry Hadfield of the LVMPD office of public information told MMAjunkie that the alleged victim was female. Hadfield said officers responded to a call and were dispatched to a Las Vegas residence at approximately 7:20 p.m. PT.

The person with knowledge of the case told MMAjunkie that 12 units were dispatched to the scene, the alleged victim was transported to a local hospital and Diaz was combative with officers during his arrest.

Diaz’s bail was set at $18,000. He remains in custody and cannot post bail until after a court hearing scheduled for Saturday at 9 a.m.

When asked for comment, UFC officials said they were aware of the incident.

“UFC is aware of the recent arrest of middleweight athlete Nick Diaz,” the statement read. “The organization does not tolerate domestic violence and requires all athletes to adhere to the UFC Fighter Conduct Policy. Every athlete is deserving of due process, and this situation, as with any official allegations, will be duly reviewed and thoroughly investigated by an independent party.”

News of Diaz’s arrest comes on the heels of his younger brother, UFC star Nate Diaz, being investigated by the Sacramento, Calif., Police Department for an alleged assault on Clay Guida during a Combate Americas event held May 11.

Nick Diaz, who’s been coy about retirement from MMA, became eligible to fight last month after he accepted a one-year suspension from the U.S. Anti-Doping Agency for missing three attempted drug tests during a 12-month span.

Diaz, 34, hasn’t fought since Jan. 31, 2015, when he lost to Anderson Silva at UFC 183, a result that was later overturned to a no-contest because Silva tested positive for performance-enhancing drugs and Diaz tested positive for marijuana.
