Workers on Tuesday set fire to a bus of a readymade garments (RMG) factory on the Nabinagar-Kaliakoir road at Zirani following a rumour over death of one of their fellows in a road accident.
They also blockaded the Nabinagar-Kaliakoir road for half an hour.
Sub-inspector of Chakrabarty police camp Musfiqur Rahman said Shahin, worker of Hamim Group, was hit by a Pabna-bound clothes-loaded bus of Nabi Textiles Mill in the area at about 7:30am.
Injured Shahin was admitted to a local hospital.
As a rumour spread that Shahin died in the accident, the garment workers flew into rage and set the bus afire.
Later, a fire fighting unit rushed in and doused the blaze.
