It also arrested the factory owner Asaduzzaman, a former Eastern Cables official, and awarded financial penalty of Tk 2 lakh, in default he has to suffer six months' imprisonment.

Acting on a tip-off, the mobile court raided RR Cables, housed in a semi-pucca (brick wall-tin roof) building at Bibirhat under Panchlaish Police Station, sources said.

The court found that substandard PVC cables and super enamel copper conductors were being manufactured at the factory using fake seal of Bangladesh Standards and Testing Institution (BSTI).

The factory, which does not have BSTI licence, had been marketing its products without going for any standard testing, sources said.

Chittagong Port Authority Magistrate Mohammad Munir Chowdhury led the drive with the help of police and BSTI and Eastern Cables officials.
