The Tennessee Sports Wagering Council fined a sportsbook $50,000 for operating illegally.
The council also encouraged anyone using Bovada to withdraw their funds immediately.
The council sent Bovada cease and desist letters to a Curaçao address but did not receive a response. Bovada was told in the letters to allow Tennessee bettors to withdraw their funds.
Investigators placed bets using Bovada just a week ago, according to a news release from the council.
