Madhavi Adak, the mother of BJP worker Piru Adak, died early on Tuesday after goons allegedly belonging to the Trinamul Congress had beat her up at Goghat late on Monday night.

The BJP has alleged that Madhavi was assaulted when she had come out to save Piru from the hands of the goons.

Piru, who had joined the BJP after quitting Trinamul following the 2018 panchayat polls, was sitting with fellow party workers near his residence in Khushiganj. A little after 10pm on Monday, a gang of about 50 goons arrived on 25 motorbikes.

Local residents said the goons were armed with sticks, iron rods and pistols.

“The goons were Trinamul supporters and they attacked Piru and other BJP workers who were sitting together after putting up BJP flags and banners. The goons started to chase away our boys. While others fled, Piru couldn’t,” said an eyewitness.

Goghat voted on Tuesday.

Hearing the commotion, Madhavi arrived on the scene and tried to save her son. While the goons couldn’t get hold of Piru, they attacked his mother instead. The BJP alleged that Madhavi was beaten with blunt objects like iron rods and the butt of a pistol.

Piru said while they had requested the police to help his mother, they refused.

Goghat’s BJP candidate Biswanath Karak said the party had lodged a police complaint. BJP workers staged a demonstration alleging police inaction.

Trinamul, however, denied any connection with the incident.

“This might just be a case of normal death. We believe they are trying to politicise the issue on poll day,” said Majumdar, rejecting charges of his involvement.
