Immigration police detained an American citizen Wednesday on suspicion he sent a letter to a local newspaper that caused security concerns for the US embassy, police said.
Gerald Francis Forbes, 63, a former US Marine, was being held and could be deported, though he had not yet been charged with a crime, Lt. Gen. Khieu Sopheak, a spokesman for the Ministry of Interior said.
Cambodian police and military units were deployed late Monday in response to a letter that constituted a security concern, officials said Tuesday.
US embassy officials said they did not consider the letter a credible threat.
