The police have arrested two men for allegedly impersonating as policemen and trying to rob two Myanmar nationals here yesterday.

Johor Baharu Selatan Police chief ACP Sulaiman Salleh said they were arrested by five police motorcycle patrolmen at 8.15pm at a house in Jalan Sentosa, Larkin, as they were beating up the Myanmar nationals with a stick.

He said the two suspects had identified themselves as policemen to the Myanmar nationals by showing them certain red cards.

"They started beating their victims with a stick and ordered them to produce their passports," he said in a statement.

Sulaiman said the motorcycle patrolmen also seized a stick, a police authority card in the name of one of the suspects and a motorcycle.

The two suspects tested positive for amphetamine and were found to have been involved in robbery and drug-related offences, he said.
