A video circulating on social media has shown Bharatpur Trinamul Congress MLA Humayun Kabir lashing out a police officer for “setting with” three local party leaders, who according to the legislator, owed secret allegiance to Opposition parties and had “fixed” to get him defeated in the recent Assembly polls.

The video was recorded in Trinamul’s Bharatpur 1 block office on Saturday and the three leaders who faced Kabir’s wrath were Mohammed Azharuddin, Noor Alam and Sanjay Sarkel.

Sources said the outburst was likely to be the culmination of a long-standing tiff dating to Kabir’s tenure as Rejinagar MLA, where Kabir, a native of Shaktipur, was reportedly browbeaten for being an outsider to the area.

“Kabir has a standing resentment against these block leaders and has claimed he has sufficient proof that they have been conspiring with the Opposition, namely the BJP and Congress,” said a local source who was present during a meeting of Trinamul workers in the Bharatpur party office on Saturday.

Kabir accepted the authenticity of the video and explained to reporters that his demand was for the party to remove the trio from the block committee during the upcoming overhaul.

“I am waiting for a formal declaration from the party stating the same, as I have put my claims in writing,” said Kabir.

“I am stating in no uncertain terms that the administration will be held responsible for any future problems stemming from this trio unless they are acted upon soon,” he added.

In his diatribe against officer-in-charge at Bharatpur police station Raju Mukherjee, Kabir said his “dalaali (profiteering)” was “unbefitting” of a cop. “I am demanding a reasonable response from Mukherjee within 48 hours,” Kabir is heard proclaiming in the video, adding that Bharatpur police station would be picketed otherwise.

Mukherjee and senior Murshidabad district police officers declined comments.

District Trinamul functionaries said the leadership in Calcutta would react to Kabir’s remarks.
