Sam Rainsy Party Senator Hong Sok Hour, who was arrested early this morning, has been sent to the Phnom Penh Commissariat following an interview in Phnom Penh’s Municipal Court this afternoon.

The Senator was accused of treason by Prime Minister Hun Sen in a speech on Thursday for allegedly publishing an altered version of a 1979 treaty between Cambodia and Vietnam on his Facebook page. He was arrested by a group of armed police at 6am this morning from the house of CNRP MP Yon Tharo, and there was a large presence of armed police surrounding the court throughout his appearance. He will be detained in the Phnom Penh Commissariat overnight and interviewed further by a prosecutor tomorrow.
