Former UFC fighter Chael Sonnen reportedly told police he doesn’t remember an altercation in a Las Vegas hotel late last year that has him facing several charges.

Sonnen, 44, was charged earlier this month with one felony count of battery by strangulation and 10 misdemeanor counts of battery after he allegedly attacked at least five people at a Four Seasons Hotel in Las Vegas Dec. 18.

After the attack, Sonnen told police that he and his wife had taken Ambien and "did not have memory of anything," according to the Las Vegas Review-Journal. 

Sonnen reportedly asked police if everyone involved was OK, and his wife told authorities that she was asleep "for the entirety of the brawl," waking up only as security guards were escorting her away.

On Friday, Christopher and Julie Stellpflug filed a lawsuit against Sonnen, claiming he repeatedly punched them in a hallway of the hotel around 7:30 p.m. Sonnen is accused of choking Christopher as Julie "continued to yell and scream for help," an arrest warrant stated. Sonnen then threw Julie against a light fixture and punched her in the face, she told police. 

Soon after, a security guard, a hotel engineer and another man staying at the hotel all attempted to intervene. According to an arrest warrant, Sonnen punched the security guard in the throat and punched the engineer in the face. Police said at least three people were hospitalized.
