An award-winning Cambodian journalist who was arrested on charges of inciting social unrest was freed on bail on Thursday, a day after the government released a video of the investigative reporter apologising.

Mech Dara, who is known for exposing corruption and human trafficking, had been held in pre-trial detention since Oct. 1, and faces up to two years in prison. His arrest drew concern from rights groups and the U.S. government.
