A Dhaka court on Friday placed three accused on an eight-day remand in a case filed for abducting Jhenaidah-04 lawmaker Anwarul Azim Anar, who was later killed in Kolkata on May 13.
Judge Dilruba Afroz Tithy of the Chief Metropolitan Magistrate Court passed the order as detectives placed them before her court and sought a 10-day remand.
Public prosecutor Abdus Sattar Dulal, who stood for the state in the court hearing, disclosed the information.
The three accused are Amanullah Sayed alias Shimul Bhuiyan, Shilasti Rahman and Tanvir Bhuiyan.
Earlier on Thursday, Dhaka Metropolitan Police additional commissioner Harun Or Rashid, also the DB chief, showed the trio arrested in the case.
Mumtarin Ferdoush Dorin, the daughter of the slain lawmaker, lodged the lawsuit with the Sher-e-Bangla Nagar police station in Dhaka on Wednesday afternoon.
Shimul Bhuiyan, a leader of Purbo-Banglar Communist Party, changed his name as Amanullah and obtained a passport to perpetrate the killing in Kolkata and dodge law-enforcers, according to detectives.
The killers planned the murder months ago and held multiple meetings in two houses, owned by mastermind Aktaruzzaman Shahin, at Gulshan and Bashundhara.
Shahin, a Bangladeshi-born American citizen, fled to Nepal after the murder, they said.
Talking to a TV channel, the kingpin behind the murder, however, denied his involvement.
According to the case statement, Mr Azim left his official residence on Manik Mia Avenue for his village home in Jhenidah on May 09.
She last spoke with him over phone around 4:45 am on May 11, which was later found switched off.
The investigator of the case said Mr Azim was killed in Kolkata on May 13.
The killers dismembered the body first and mutilated it in such a way that it would be tough to identify it.
UNB adds: The Kolkata police have hit the field to find the missing body parts of the slain lawmaker.
"Efforts are being made to recover the fragments of MP Anar's body with the help of Siam, who was arrested in India," Mr Harun told reporters on Thursday night.
Meanwhile, a three-member team of the Indian intelligence team reached Dhaka on Thursday to investigate the sensational murder.
In the evening, they met the DB chief at his office on Bailey Road and discussed enquiry-related matters.
Members of the Indian agency interrogated the three Bangladeshis involved in the murder.
"The arrestees confessed to the Indian intelligence…," stated Mr Harun.
MP Azim went to Kolkata on May 11 for his medical treatment and he remained untraced since May 14.
On Wednesday, home minister Asaduzzaman Khan disclosed to the media that Mr Azim was brutally killed in a flat in New Town of Kolkata.
