Two escaped prison inmates from Tennessee may be traveling through parts of Mississippi, the U.S. Marshals office warned Monday.

Antoine Thomas and Michael Bolden are sought after escaping the custody of the Dyer County (Tennessee) Sheriff’s Office.

U.S. Marshals said the pair escaped on Sunday after they assaulted a corrections officer.

Both men reportedly have a violent criminal history and are known to be gang members.

Thomas is believed to belong to the Mafia Insane Vice Lords and Bolden to the Bloods street gang.

The pair are believed to be traveling through the north Mississippi area, perhaps near Tupelo. The two men are considered dangerous. If you see them or know anything about their whereabouts, you’re asked to call 911.
