"GRP constable Md Musharaf Hossain was arrested after the brother of the dead hawker - Binod Bihari Sadhukhan - alleged that he had beaten Binod to death," Chandannagar SDPO Tathagata Bose said.
However, the hawkers of Chandannagar station also beat up and injured Hossain and he was admitted to Chuchura Imambara Hospital.
The incident happened at about 12.45 pm when the constable asked Sadhukhan to leave the station premises as he felt sick during intense heat, Bose said.
Sadhukhan, a resident of Teena Para in Bhadreswar, was a newspaper hawker.
His body was found outside the station after he was asked to leave the station by the constable, SDPO said.
Other railway hawkers damaged railway property in the station and beat up the constable after Sadhukhan's body was found, Bose said.
