Kolkata: The West Bengal CID interrogated Mohammad Siyam Hussain, who was apprehended by Nepal Police and subsequently extradited to India, in connection with the agency’s probe into the murder of Bangladesh MP Anwarul Azim Anar. 

Hussain was also taken to the apartment in the New Town area near Kolkata, where Anar was last seen on May 12, to aid the CID in locating the remains of the Bangladeshi politician and the tools used to commit the crime. Hussain, the key suspect, was arrested by the Nepal Police and subsequently handed over to Indian authorities on Friday.

"We are questioning Hussain. He was also taken to the New Town flat and nearby areas to look for the Bangladesh MP’s body parts. He will assist us in tracing the murder tools as well,” the CID officer said.

Hussain was brought to West Bengal on Saturday evening and sent to 14-day custody of the CID by a local court in Barasat in North 24 Parganas district.

Efforts to locate the missing MP, who reportedly arrived in Kolkata on May 12 for medical treatment, have been underway since Gopal Biswas, a resident of Baranagar in north Kolkata and an acquaintance of the Bangladeshi politician, filed a complaint with the local police on May 18.

Anar had been staying at Biswas' residence upon his arrival.

In his complaint, Biswas mentioned that Anar left his Baranagar residence for a doctor's appointment in the afternoon of May 13 and was expected back home for dinner. However, Anar's disappearance prompted Biswas to file a police complaint.
