Authorities are on the hunt for New Orleans-based rapper Mystikal, who is accused of participating in a 2016 sexual assault.

According to KSLA Fox 8, the alleged incident took place in Oct. 22 at the Clyde Fant Memorial Parkway in downtown Shreveport, Louisiana. Investigators reportedly collected physical evidence as well as statements from the victim and witnesses before issuing a warrant for the 46-year-old artist’s arrest. He was charged with one count of first degree rape, with bond set at $2 million.

Fox 8 reports one man, Averweone Holman, has already been arrested in connection with the sexual assault case. Authorities are now seeking information regarding the whereabouts of Mystikal and his associate Tenichia Wafford, who is accused of trying to convince the victim to drop all charges against the rapper and Holman. Wafford is facing one count of accessory after the fact to first degree rape.

Shreveport authorities are asking anyone with information about Mystikal and Wafford’s location to contact Crime Stoppers at 318-673-7373 or the website Lockemup.org

In 2002, Mystikal was arrested on charges of aggravated rape and extortion after he forced his former hairstylist to perform oral sex. He later pleaded guilty to the charges and was sentenced to six years in prison. Following his release, he was required to register as a sex offender. He was arrested again two years later on a misdemeanor charge of domestic abuse battery.
