Gerald Francis Forbes, the former US Marine who sent a letter describing a potential attack on the US Embassy to a Phnom Penh newspaper, will be deported, officials said.
Forbes has been held since last week, following his confession he sent a letter to the English-language Cambodia Daily warning of an attack on the US Embassy.
Embassy officials have said they did not consider the letter a credible threat.
Lt. Gen. Thong Lim, director of the Ministry of Information's immigration department, said Saturday the government would deport Forbes.
"Because our immigration law also includes deportation, we are implementing our immigration law," he said.
