A 44-year-old trader from Howrah’s Shibpur, who used to deal in tarpaulins in Calcutta’s Burrabazar, was allegedly killed by unidentified persons in his ancestral home in East Burdwan’s Raina on Friday night.

Police sources said Sabyasachi Mondal had come to his ancestral home at Dariyapur village on Friday with one of his friends, a driver and an aide.

Sabysachi’s father, Deb Kumar Mondal, 68, has lodged a complaint with the Raina police accusing his brother and nephews of the murder.

Sources said Sabyasachi’s friend Rajveer Singh, 42, was alerted by his screams around 9pm. “I found at least four persons stabbing Sabyasachi with sharp weapons. They left the place after killing my friend.”

“We own a tarpaulin business in Burrabazar that my son used to run. There has been a long-running conflict over property and ancestral business with my brother and his sons. We want punishment for those behind the murder,” said Deb Kumar.

“We have started a probe,” said Aminul Islam Khan, SDPO, Burdwan south.
