Authorities on Tuesday released on bail four people accused of attempting to incite the country’s armed forces to topple the government of Prime Minister Hun Sen, though rights groups said the charges against the suspects should be dropped altogether due to a lack of evidence. Hy Borin, Tut Chanpanha, Sok Dalis and Lim Lypheng were all arrested on Thursday and charged by the Phnom Penh Municipal Court two days later with incitement for allegedly planning to give soldiers and police yellow roses accompanied by stickers urging them to “turn your guns against the despot.”
