A team of the West Bengal CID visited Bangladesh on Thursday to interrogate the three accused who were arrested by Bangladesh police in connection with the MP Anar murder case.
The WB CID police left the country on Friday.
The accused were identified as Amanullah Aman, Celesty Rahman and Faisal Ali. Although the body parts of the victim are yet to be recovered, the woman and the butcher have been arrested along with two others following parallel probes by police in West Bengal.
MP Anwarul Azim is suspected to have been lured to a rented flat in New Town area of Kolkata by using a woman as a bait.
He was smothered to death before a butcher skinned him and chopped his body into small pieces for disposal at various places within the city limits, according to investigators.
Although the body parts are yet to be recovered, the woman and the butcher have been arrested along with two others following parallel probes by police in West Bengal and the Dhaka Metropolitan Police.
The DMP produced three arrested persons, including the woman suspect Celesty Rahman, in the Mahanagar sessions judge court there on Friday.
"Simul Bhuiyan alias Amanullah, Celesty Rahman and Tanvir Bhuiyan were produced in court and remanded in police custody for eight days. Interrogation of the accused persons will reveal the details.
So far it is suspected that the murder conspiracy was hatched by Akhtaruzzaman alias Shahin, an old friend and business partner of the victim," said Md Abdus Sattar Dulal, additional public prosecutor.
