A BJP worker was beaten to death allegedly by unknown goons in Birbhum’s Nalhati on Friday afternoon.

The BJP has labelled the murder as a fallout of post-poll violence and accused Trinamul goons of killing Manoj Jaiswal, a construction material trader.

Jaiswal, 38, had joined the saffron camp ahead of the Assembly polls. On Friday evening, his body was found near Nalhati’s Madhura village.

“So far we have not found any political connection behind the murder. We have started a probe and suspect business or personal rivalry could have led to the murder,” said Nagendra Nath Tripathi, the Birbhum police chief.

“We will arrest the culprits soon,” Tripathi added.

Sources said Jaiswal, a native of Calcutta, had been staying in Birbhum’s Nalhati for the past 10 years for business. He had joined the BJP a month before the Assembly elections.

“He was our active supporter and has been killed by Trinamul goons as he worked for us in the recent Assembly polls,” said Dhruba Saha, BJP’s Birbhum president.

Ashok Ghosh, the Nalhati block president of Trinamul, rejected the allegation and said: “Let the police investigate the case and find the culprits. We are sure there is no political link to the murder.”

The car of Bankura MP Subhas Sarkar was ransacked when he was on the way to a village near Bankura town on Friday morning.
