Police fired rubber bullets into an unruly mob in Rangpur's Thakurpara union on Friday afternoon, in order to disperse an attack on a local Hindu neighbourhood.
The mob retaliated and charged at the police, leading to a violent clash.
Around 25 people were injured that day, some of them hit by the rubber bullets fired by the police. The 27-year-old Hamidur Rahman, who succumbed to his injuries at the Rangpur Medical College Hospital that evening, was the only fatality.
Rangpur police identified him as a Jamaat-e-Islami activist and said he took part in the attack.
However, Hamidur's family is saying he was never involved with politics and merely happened to be in the area, on his way to work.
Hamidur was the eldest of three brothers and second among six siblings. His father Abdur Razzak, 65, is a rickshaw puller in Dhaka and Hamidur was a street hawker stationed at the Rangpur Medical College Hospital crossing.
According to Razzak, Hamidur was the guardian of the family, who looked after the whole family in absence of the father.
“My son never went to school and was also never involved in politics. He started working for his family at a very early age,” he said.
Hamidur had two daughters - Umme Habiba Bristy, six, and Hawa Moni, two. Since his death his wife Moslema has been so sick that she has been unable to leave her bed.
“We have decided that I will come back to the village and do something here. Hamid was the main bread earner,” he said.
According to the family, on Friday Hamid left home for work and after reaching Sohel Shah Bazar found that there were no vehicles plying on the road.
He decided to go to Paglapir bus stand on foot instead of waiting. Afterwards the family learned that he was killed.
“I do not I know if my son was targeted or killed accidentally, all I know is that he is being blamed wrongfully, and right now I have no one beside me,” Razzak said.
“The government is helping the Hindu people because they were attacked, but my son was killed because of these attackers and we are not getting any compensation,” he said.
“I could not perform his janaza properly because there is police everywhere and people were afraid to take part in the janaza.”
In Sohel Shah Bazar and nearby Lalchadpur and Muchia Para neighbourhoods, most of the men were missing, apparently due to a fear of arrest.
