The raid took place in a small park behind a Puchong Tesco store, where scores of refugees from Burma, Indonesia and Bangladesh take shelter, according to a leader of Alliance of Arakan Refugees (AAR) in Kuala Lumpur.
"Many Arakan refugees are among those arrested yesterday. Malaysian police checked their identifications and some UNHCR card holders were released immediately while others having only a refugee card issued by their community were taken away in a lorry," said the Arakan leader.
"Some arrestees, mainly from Indonesia and Bangladesh, were caught holding 'fake' UNHCR cards," he added.
It is known that the arrestees were kept in the Puchong Detention Centre and that they may be transferred to Bukit Jalil Dentention Centre today.
The Alliance of Arakan Refugees is said to have written to the UNHCR in regards to the incident yesterday.
Puchong, a major town in the Petaling district of Selangor, is situated midway between Kuala Lumpur, Malaysia's political capital, and Putrajaya, the administrative capital.
