Thirty people were injured in a clash between police and garment workers at BSCIC industrial area in Fatullah of Narayanganj district on Sunday.
Quoting witnesses, police said a group of workers of Abanti Colour Tex Limited blocked Dhaka-Munshiganj road around 9:30 am after placing bamboo, sticks, electric poles and logs demanding payment of their dues.
A two kilometer long tailback was created following the blockade.
On information, police rushed to the spot and the clash started around 12:30 pm when they tried to disperse the workers.
A chase and counter-chase took place in the area.
Police lobbed tear gas shells and fired rubber bullets and used water cannons to bring the situation under control.
Workers said the factory was declared closed on April 8 without clearing the dues for the month of March.
The owner of the factory earlier assured that they will pay their dues through mobile banking before Eid-ul-Fitr but the workers did not get their salary.
Vehicular movements in the area came to normal around 4 pm.
Contacted, Aslam Sunny, director of Crony group, said they have cleared the bonus of the workers but failed to provide the salary of the month of March due. He said they will pay the salary by Wednesday.
Additional police have been deployed in the area to avert further trouble, said Taslim Uddin, in-charge (investigation) of Fatullah Model Police Station.
