The West Bengal CID on Sunday recovered parts of human bones near a canal in South 24 Parganas district, during a search operation in connection with its probe into murder of Bangladesh MP Anwarul Azim Anar, a senior official said.

The specimen was found on the south-eastern bank of Bagjola canal in Bhangar’s Krishnamati village, following the interrogation of Mohammad Siyam Hussain, a key suspect in the case who was arrested by the Nepal Police and extradited to India, he said.
