The infighting in the Trinamul Congress in Hooghly district reached a new low after “unknown” people vandalised the office of the party’s Balagarh MLA Manoranjan Byapari late on Wednesday night.

While Byapari blamed his rival in the party, Hooghly zilla parishad member Runa Khatun, and her husband Arijit Das for the violence, the couple lodged a police complaint against the MLA for allegedly tarnishing their image.

“Finally, my apprehension has come true. Runa Khatun and her husband Arijit Das attacked my office in Hooghly’s Jirat. They broke the window panes and the door of the office. They also threw away party flags and photographs of Didi (Mamata Banerjee),” Byapari wrote on social media.

Byapari had on Wednesday gone public apprehending an attack on his life and accused Khatun and her group of conspiring against him. “I was in Calcutta last night. I would have been killed if they had spotted me in Balagarh last night,” he said.

Rejecting Byapari’s allegations, Khatun said: “It is the MLA who started throwing muck at me. He has been making false allegations against me and my husband.”

Byapari hasn’t filed a police complaint in connection with the attack on his office.

The police said “unknown” people had attacked the office.
