Romania’s gambling regulator has temporarily suspended two gaming licenses for as-yet unexplained reasons.

On Thursday, Romania’s Oficiul National Pentru Jocuri de Noroc (ONJN) regulatory body announced that it had suspended the licenses of online gambling operator Sea-Bet Limited and fixed-odds betting licensee Bet Club Sistem SRL. The two companies are part of the same group.

Sea-Bet, which is based in Malta, operates online in Romania under the Publicwin.ro domain and controls a network of retail betting operations in Romania under the Publicwin brand.

The suspensions were issued on September 18, but didn’t take effect until Wednesday. Neither of the ONJN’s official notices offers reasons for the suspensions.
