We don't know if these specific accusations are true. However, we have heard stories like this for decades - it's one of the central incidents of Tom Wolfe's A Man In Full. The conservative press has been very hard on colleges for closed-door, kangaroo court justice for accused males in sexual assault cases, attributing this to SJW-style justice that too-readily believes the female and denies men their rights.
Maybe so. But colleges have another reason for handling these things themselves rather making everyone go to the police and the regular courts. It also allows them to protect accused athletes, another source of prestige and revenue.
