The champion U.F.C. fighter Jon Jones turned himself into the authorities on Monday night in connection with a hit-and-run crash, officials said.
Bernalillo County said that Jones was booked into the Metropolitan Detention Center and released a while later.
An arrest warrant signed by the police said Jones faced a felony charge of leaving the scene of an accident involving death or personal injuries.
According to police, witnesses said that Jones ran from a crash on Sunday that hospitalized a pregnant woman but quickly came back to grab “a large handful of cash” from the car.
