The CID team probing the murder of BJP leader Manish Shukla arrested another alleged assailant from Bihar on Thursday.

Based on information revealed by those arrested in the case, the CID team picked up Amar Yadav, 25, early on Thursday from an undisclosed place in Bihar. Amar is likely to be produced before a court in Barrackpore on Friday.

With this, police have so far arrested six persons in connection with the case. Manish, a former councillor of Titagarh Municipality in North 24-Parganas, was gunned down on October 4 in Titagarh by four bike-borne assailants.

Amar had allegedly been sent by Subodh Singh, the alleged mastermind, as a technical hand. Amar’s job was to check firearms, a CID officer said.

Earlier, CID took into custody Sujit Rai, 26, and Roshan Yadav, 26, sharpshooters from Punjab. Police had arrested Subodh, who allegedly planned the murder from a jail in Nalanda, and a Titagarh businessman as suspect for his enmity with Shukla.

BJP MP Arjun Singh iterated Trinamul’s hand in the murder.

“Shukla’s murder was a planned conspiracy. We suspect some ruling party leaders and policemen were involved. We think the real culprits are being protected.” Trinamul has denied the allegations.
