North Klang district police chief S Vijaya Rao said the suspects, aged 20 to 40, were detained by police following a report lodged by the owner of an aluminium factory in the West Meru industrial area, near here.

All the Malaysian suspects, who have multiple criminal and drug-related records, have been remanded for five days.

The factory owner reported the premises were broken into and 180 bitcoin machines stolen in two incidents, on April 27 and May 20.

Rao said the intruders had tied up the security guards on duty before entering the factory.

He said police had seized several cars, computers, mobile phones and bitcoin mining machines during the raids.

Rao said police were seeking the help of three more men to help in their investigations. They are Tan Jian Farn (Q-Peng), 37, Herman Petrus, 41 and Abdul Rahim Mohamad Ali, 33.
