Wanchalerm, a 37-year-old pro-democracy activist, fled Thailand after the military coup in 2014 and has been a loud critic of the Prayut government. He was last seen being bundled into a vehicle by unknown men in a Phnom Penh street on June 4.
The students said it has been a whole week since Wanchalerm’s disappearance but there is no clear progress in the investigation.
The group also tied white ribbons on the Government House fence in a symbolic gesture.
