Thirteen Burmese migrant workers are among the hundreds of anti-government red shirt protesters being held by the Thai authorities, said a Burmese advocacy group in Thailand.
The Irrawaddy newspaper said the group; Thai Action Committee for Democracy in Burma (TACDB), confirmed that 13 of the 422 detained protesters identified by the Thai government earlier this week are Burmese nationals.
The Burmese detainees, all of whom are men, remain in police custody. Ten are being held at a police station in Pathum Thani Province, two others are in another province and the remaining one is in a special detention center, according to TACDB.
"We don't know if they were arrested during the protests or because they violated the recent nighttime curfew," said Myint Wai, an official from TACDB.
Lawyers representing TACDB will meet with the Burmese detainees on Monday, the group said.
Just before the start of the two-month-long protests in Bangkok, which ended last month in a deadly crackdown, Thai authorities warned migrant workers to stay away or face arrest, up to five years' imprisonment and fines of up to Bt100,000.
