Thailand’s military raided the studios of four foreign-language radio stations in Pattaya on Wednesday, closing three of them, reports Pattaya One.

Pattaya 105FM, 96FM and 89.5FM were forced off the air after being found to be in breach of rules linked to the recent military coup in the country.

When the army took over last month, they forced numerous radio and TV stations off air.  Many of them were illegal broadcasters or had political affiliations.

But while the stations had returned to air recently, after a lifting of restrictions and a night curfew in Thailand’s main cities, it is believed they may not have had permission to do so.

The navy and police teams were joined by officials from the Thai media regulator National Broadcasting and Telecommunications Commission (NBTC) for Wednesday’s raid.

Pattaya One reports that amplifiers and other broadcasting equipment was seized from each of the radio stations and the teams found irregularities at three of the stations, but didn’t describe which kind.

The stations told the paper they hope to continue dialogue with the NBTC.

Meanwhile several foreign language stations in Phuket also remain off air following the military crackdown on broadcasting.

Asia Radio Today was informed that one station on the island returned to air on Saturday but was closed down again within a few hours.
