BANGKOK - The Thai military junta on Wednesday released several leaders of the United Front for Democracy against Dictatorship (UDD), or "red shirts," who had been detained for seven days, while former premier Yingluck was confirmed not under house arrest in Bangkok.

The National Council for Peace and Order (NCPO) released UDD chairman Jatuporn Prompan, Nuttawut Saikuar, Pracha Promnog, Virakarn Musigapong Weng Tojirakarn and Thida Tavonseth.

Meanwhile, Thai former Prime Minister Yingluck Shinawatra is confirmed staying in Bangkok and not under house arrest, the Bangkok Post on Wednesday quoted a reliable source at NCPO as saying.

Yingluck is allowed to travel freely in the country, but not to leave Thailand, and has to inform the NCPO if going outside Bangkok, the source said.

Yingluck was held in army custody for one night at the 1st Division, after reporting to the NCPO last Friday under the request of the military junta.

Thai Army Commander-in-Chief Gen. Prayuth Chan-ocha, who was later endorsed as chief of the NCPO, declared a coup last Thursday, and summoned prominent figures, including politicians, scholars, businessmen, among others.
