Four people were killed and 10 others, including two highway policemen, injured after being rammed by a covered van in Chattogram's Mirsarai upazila early Thursday.
The accident took place in the Sonapahar filling station area of the Dhaka-Chattogram Highway around 1:30am.
All the deceased Mehedi Hasan, Suman, Sheikh Farid, and Abul Kashem, hailed from different areas of Mirsarai upazila.
"Prior to the deadly accident, an accident took place on the busy highway involving a Chattogram-bound bus and a Dhaka-bound lorry," Zorarganj Highway Police Sub-Inspector Kamrul Hasan told The Business Standard.
"Following the previous accident, a team of highway police went to the spot as the drivers of two vehicles and passengers of the bus got into a heated debate although there were no casualties," he said.
At that time, a covered van rammed into the people gathered in the area, killing four on the spot and injuring 10 others, the police official said.
The injured, including Zorarganj Highway Police Assistant Sub-Inspector Md Mustafa, Constable Abdul Awal, pedestrians Rafiq and Sheikh Ahmed, were taken to Mirsarai Upazila Health Complex initially.
"Later, all of the injured were sent to Chattogram Medical College Hospital for better treatment," said Palash Kumar Dey, physician of Upazila Health Complex, adding that the condition of ASI Mustafa is critical.
