Demanding three-month unpaid wages, workers of TNZ Apparels Ltd have again blocked the Dhaka-Mymensingh highway in Gazipur`s Maleker Bari area on Sunday for the second consecutive day.

They said the authorities assured them several times to pay the dues but, later, failed to pay the overdue wages. This time, they will not leave the road until their dues are met.

Meanwhile, fearing sabotage, 30 factories in Gazipur were declared closed.

Army personnel met with the protesting workers but did not manage them.

Gazipur Metropolitan DEputy Police Commissioner (Traffic) Ibrahim Khan said, "The workers were protesting blocking the highway overnight. A 30-kilometre tailback was created on both sides of the highway due to the road block. Passengers were bound to take alternative ways."
