Bangkok:
Thailand's main press association has voiced concern that undercover police appear to be posing as journalists after a video circulated showing a man with official press ID arresting an anti-coup protester in the capital.
The Thailand Journalists Association said Monday the tactic would have an "immense impact" on the safety and credibility of journalists and urged police to revise their strategy.
The video posted on the website of the Matichon newspaper shows several men escorting a woman to a motorcycle, as she calls for help and asks them not to arrest her.
One of the men is wearing a black badge around his neck that says "PRESS" along with a green cloth that looks like the arm bands issued by the journalists' association for reporters to wear at public protests.
