Russian mixed martial artist Usman Nurmagomedov’s attack on former UFC bantamweight champion Merab Dvalishvili in Abu Dhabi on Wednesday led to the arrests of eight people, per the National News and the Abu Dhabi Police Department.

Dvalishvili was in the midst of an interview in the lobby of the Yas Hilton hotel when Nurmagomedov and his comrades approached him from behind and slapped him in the face.

A brawl quickly broke out, leaving Dvalishvili and his friend Saba Lazishvili hurt.

All involved were taken into custody and fined, with eight defendants being sentenced to six months in prison for disturbance of public security, causing panic and endangering lives.

Dvalishvili and Lazishvili were released from a UAE detention center Friday, where they had been held since the Wednesday brawl, per Ariel Helwani.

Real American Freestyle CEO and co-founder Chad Bronstein reportedly worked with authorities to have them released.

Nurmagomedov was sentenced to six months in prison.

The PFL lightweight champion, was in the UAE to coach his brother Umar, who is scheduled to battle Urijah Faber during RAF Abu Dhabi Saturday.

Dvalishvili was also scheduled to partake in the event, and his match will go on as scheduled while Umar has been removed from the card.

Usman was also banned from attending the event this weekend before his sentencing.

Video footage of the brawl circulated online Wednesday, as well as a message from a bloodied Dvalishvili sharing that he was surprise attacked by Usman and multiple men.

Among the eight people arrested were those who recorded the incident at the hotel, who were fined and ordered to leave the country, per Yahoo.
