Ex-boxing champ Victor Ortiz -- who appeared on "Dancing With the Stars" -- has been charged with 3 counts of felony sexual assault, including rape ... officials say.
The 31-year-old -- who also had roles in 'Expendables 3' and "Southpaw" -- surrendered to authorities in Oxnard, CA on Tuesday.
According to court records, the alleged incident took place inside of a home in Oxnard on March 19. The female accuser contacted police that same day and filed a report accusing Ortiz of sexual assault.
The Ventura County District Attorney's Office has charged the boxer with 3 felony counts -- forcible rape, forcible oral copulation and forcible digital penetration.
He was booked, posed for a mug shot, and bail was set at $100,000.
Ortiz is slated to fight Sunday night in Ontario -- but we're guessing that will likely be called off very soon.
It's not the first time Ortiz has been in trouble with the law -- he was arrested for DUI back in 2016. And in 2015, he was arrested after allegedly attacking a man at a Kenny Chesney concert at the Rose Bowl.
