Police say a Mississippi university president lied about his identity when they arrested him on prostitution charges over the weekend.

William Bynum Jr., 57, was one of more than a dozen people arrested in a prostitution sting led by Clinton Police.

Bynum, the Jackson State University president at the time of his arrest, was charged with procuring services of a prostitute, providing a false statement of identity to police and simple possession of marijuana.

When asked if Bynum tried to tell police he was someone else, Clinton Police Chief Ford Hayman confirmed Bynum attempted to cover up his identity.

“Without getting into particulars, yes, he was charged with that — providing a false identity,” Hayman said, the Associate Press reported.

Bynum submitted his immediate resignation Monday.

Hayman said the people arrested responded to an online ad for prostitution services. Each was met by an undercover police officer at a hotel near Interstate 20.

Bynum was selected as Jackson State University’s president in 2017. Previously, he served as president at Mississippi Valley State University.

Jackson State is a public, historically black university based in Jackson. The university is one of the largest historically black colleges and universities in the country.

JSU was founded in 1877 as Natchez Seminary and eventually relocated to the state capital and was renamed.

Bynum was Jackson State University’s 15th president.
