Police are investigating UFC heavyweight champion Jon Jones for allegedly assaulting and threatening to kill a drug testing agent, per multiple reports on Saturday.

Crystal Martinez, an agent for Drug Free Sport, filed a report with Albuquerque police on April 5 after visiting Jones' home on March 30, according to MMA Fighting. She was there to collect a sample as part of the UFC’s anti-doping program, which transitioned into CSAD in December 2023 following USADA's departure.

Details in the police report include Martinez claiming to have been "terrified" but unable to call authorities because Jones had allegedly taken her phone.
