3:31 PM PT -- Rhoden was released from custody late Tuesday. Officials say he bonded out.
12:41 PM PT -- TMZ Sports has obtained Rhoden's mug shot after he was booked Tuesday.
Bodybuilding superstar Shawn Rhoden -- the reigning Mr. Olympia -- just turned himself in to authorities in Utah and pled not guilty to multiple felony rape charges, TMZ Sports has learned.
As we previously reported, Rhoden -- who goes by Flexatron -- is accused of raping a female bodybuilder during a hotel encounter back in Oct. 2018.
According to court docs, Rhoden's accuser claims Rhoden forced himself on her inside his hotel room - and despite repeated pleas to stop, he refused. She claims he eventually stopped and let her leave the room.
Now, Rhoden's attorneys say the bodybuilder voluntarily turned himself in to authorities Tuesday -- after negotiating his bail to be reduced from $750k to $250k.
Shawn's lawyers say he "vigorously denies the charges" and "looks forward to being cleared of these false accusations in court."
Jail records confirm Rhoden was formally arrested and booked. The 44-year-old is listed at 5'10" and 265 pounds.
