Mystikal's Rape Charges Dismissed Due to Not Enough Evidence

Mystikal insisted he wasn’t guilty of rape ... and now it looks like a grand jury agreed with him 'cause TMZ's learned his rape charges have been dismissed.

A spokesperson with the Caddo Parish District Attorney's Office tells TMZ ... a grand jury found there wasn't enough evidence to move forward with the charges and decided to dismiss the charges against Mystikal.

Mystikal's attorney, Joel Peace, tells TMZ ... the charges went away because “new scientific evidence emerged causing the Grand Jury to take a second look at the rape allegations made against [him]."

As we reported .... Mystikal turned himself in back in August 2017 when he was booked for first-degree rape and second-degree kidnapping stemming from a 2016 incident involving a woman at a casino where he was performing. He spent 18 months behind bars but, thanks to a new recording deal, he finally posted $3 million bond in February to secure his release from a Louisiana prison.

Prosecutors offered a plea deal before the case ever went to trial but Mystikal rejected the offer. Why? Mystikal's defense teams believed the alleged victim had major credibility issues and were more than ready to battle it out in court.
