"America's Next Top Model" judge Rob Evans has turned himself in to police after allegedly beating up another man so badly, the guy ended up in the hospital ... sources close to Evans tell TMZ.
We're told Evans turned himself in at the Beverly Hills PD Wednesday morning on a felony assault charge -- and was released 25 minutes later after posting $60,000 bail.
TMZ broke the story ... a warrant was issued for Evan's arrest following the fight in March in Bev Hills. Details surrounding the fight are unclear.
But sources close to Evans -- a former boxer -- tell TMZ, Evans was completely unaware of the warrant being issued until very recently. As soon as he caught wind of it, we're told he contacted his lawyers who advised him to turn himself in.
As for the fight itself -- sources close to Evans tell us the alleged victim was trash-talking Evans when he reared up as if to attack him, so Evans punched him ... and insists the punch was in self-defense.
So far, no court date has been set.
