Abdul Hannan, officer-in-charge of Ashulia Police Station, said a worker was slightly injured in the clash and he was given first aid.
The vehicular movement on the highway came to normal after one hour of suspension.
Meanwhile, a tripartite meeting was held at the Department of Inspection for Factories and Establishments on Tuesday where the authorities decided to close the 16 factories under Nasa Group from September 26, citing gas and electricity shortages, along with a lack of buyer orders.
