Garment workers attempted to block the Dhaka-Tangail highway in Gazipur's Mouchak area on Sunday morning, throwing bricks at police and bringing traffic to a standstill for around half an hour.
Police fired tear gas shells to disperse the workers and clear the highway.
The incident occurred at around 8:45am in the Telirchala area of Mouchak.
Mohammad Amjad Hossain, superintendent of Gazipur Industrial Police-2, said the situation had been largely normal since morning.
He said workers from the Lavenda garment factory arrived in the Telirchala area shortly after 8:30am but, instead of reporting for work, took to the highway and attempted to stage a blockade.
The workers remained on the road for around 30 minutes, disrupting vehicular movement. When police asked them to clear the highway, some protesters threw bricks at law enforcement personnel.
Police then fired tear gas shells to disperse the workers and restore order, Amjad said.
The workers fled the scene following the police action, and traffic movement returned to normal by 9am, he added.
