Struggling to crush the two-month old protest movement against a coup, Myanmar's military rulers are cracking down on the country's best-known celebrities to block any support for the opposition campaign.

More than 50 soldiers came to arrest Paing Takhon, a 24-year-old model and actor who had spoken out against the coup, on Thursday, his sister told Reuters. He was taken away and his current whereabouts are unknown.

Legendary actor-director Lu Min, who has starred in more than 1,000 films, was arrested in February for supporting the anti-coup movement, his wife said.
