The court seized 5,000 metre duplicate cables, T&T wire, PVC compound, television jack, monogram of Philips and Hitachi, and huge quantity of machineries before sealing the factories off.

The court, led by Chittagong Port Authority Magistrate Munir Chowdhury, found that the factories were built at a two-storey building and a semi-pucca house at the area and were manufacturing and marketing duplicate PVC cables of the companies without any licence from the concerned Bangladesh Standard Testing Institute (BSTI).

The thermal stability, diameter and thickness of insulation of the seized cables were less than the ideal measurement of the BSTI standard and also were not able to carry loads, sources said.

The cables cause electric short circuit and damage electronic goods in residences and factories, they added.

The factories were running after the name of Star Cables Factory, Bangladesh Cables Factory and Siddique Cables Factory and marketing the cables as Eastern Cables, BRB Cables, Hitachi and Philips Cord.

Chittagong Metropolitan Police (CMP) and officials of Eastern Cables and BSTI assisted the mobile court during the drive.
