Jaiprakash Khaitan, the owner of the nursing home, said that Dey had threatened several people earlier, and after Debangshi was selected for the post of secretary of the TMC-backed association, the rivalry between the duo escalated.
A complaint was lodged with the police on Sunday afternoon. SP (Birbhum) Murlidhar said the police were investigating the matter.
Dey was elected as district secretary of the TMC in 2008. Months later, the party dismissed him from the post following reports of his alleged hooliganism. Despite repeated attempts, Dey could not be contacted.
TMC MP from Birbhum Satabdi Roy admitted factionalism in the district unit. She described Dey as a criminal and accused him of “trying to hatch conspiracy” against the other faction, led by MLA Swapan Ghosh. “We have intimated party chief and stern action will be taken against Dey,” she said.
