BJP leader and former Bengal minister Shyamaprasad Mukherjee was arrested on Sunday for his alleged involvement in financial irregularities to the tune of Rs 10 crore.

Mukherjee had resigned from TMC ahead of this year’s assembly elections and joined BJP.

Police said the former Trinamool Congress MLA from Bishnupur was held following an investigation into allegations of misappropriation of money related to e-tendering and other charges when he was chairman of the local civic body in 2020.

“An investigation was carried out by the SDPO, Bishnupur into the allegations of financial irregularities of Rs 9.91 crore. Mukherjee was arrested after he failed to give satisfactory answers to queries,” Bankura SP Dhritiman Sarkar said.

The BJP’s Bishnupur organisational district president Sujit Agasthi claimed that Mukherjee had joined the saffron party before the assembly elections in the state but he was not actively involved.

“The allegations against him are of the time when he was in Trinamool Congress. Has the government woken up now?,” he said.
