Cambodian opposition lawmaker arrested for alleged use of fake border maps

Cambodian police arrested opposition lawmaker Um Sam An in the early hour on Monday in northwestern Siem Reap province for the allegations of using fake border maps with Vietnam, local media reported.

Um Sam An, a lawmaker of the main opposition Cambodia National Rescue Party (CNRP), was arrested in the province, less than 24 hours after he returned from the United States, where he had lived in exile since July last year, Fresh News service provider reported, citing a senior government official.

The lawmaker was sent to the Interior Ministry's department of anti-terrorism and transnational crimes in Phnom Penh on Monday morning for questioning.

CNRP spokesman Ou Chanrith confirmed the arrest.

"My assistant told me that he (Um Sam An) was arrested at around 1 a.m. last night in Siem Reap province," he told Xinhua.

In August last year, opposition senator Hong Sok Hour was arrested for posting a fake version of a Cambodia-Vietnam border treaty on a Facebook page.

He was charged with falsifying public documents, using fake documents, and inciting chaos to social security. If convicted, he could face up to 17 years in jail.
