On 16 June, Ly Chandaravuth, Sun Ratha and Sith Chhivlimeng were arrested in Phnom Penh’s Daun Penh district while an environmental activist Yim Leanghy was arrested in Kandal province’s Koh Thom district the same day.

Cambodian Youth Network's member said that all of them are environmental activists who work on environmental issues and are critical of the government. Their primary work involves producing short video clips about environmental issues and posting it on their Facebook page.
