Police have brought the family members of “Neo JMB” leader Maynul Islam Musa, believed to have been killed in an army operation at a militant den in Sylhet, to the north-eastern city yesterday to collect their DNA samples.

Musa's mother Sufia Begum, sister Kamrun Nahar and step-brother Khairul Islam were taken to Sylhet Osmani Medical College under police protection from Rajshahi yesterday.

Sufia's DNA sample was collected so that it could be matched with that of the body, said Zedan Al Musa, additional deputy commissioner of Sylhet Metropolitan Police (SMP).

When asked if the family was able to identify the body, the police official made no comments.

On Wednesday, family members of Monjeara Begum, believed to be killed in the same operation, could not identify her. Police collected the DNA samples of her father Nurul Islam and brother Jiabul Haque, who were taken there from Bandarban.

Monjeara used the name Marjina Begum while staying at Atia Mahal, the house in Sylhet city's Shibbari area where the army had launched “Operation Twilight”.

Suicide-vest-strapped bodies of two militants are still in the building.

Basudeb Banik, deputy commissioner of SMP, told The Daily Star that the Bomb Disposal Unit of police was yet to sweep the entire building as lots of explosives were still there.

He said the Police Bureau of Investigation and the Criminal Investigation Department of police would collect evidence and samples from the building once the bomb disposal unit finished its clean up.

Police cordoned off the building and the neighbourhood and restricted movement of people there. Gas connection in the area was restored on Wednesday.

Meanwhile, law enforcers with the help of the army yesterday destroyed what appeared to be a bomb, hours after the object was discovered in Shahi Eidgah area of the city.

Police had sealed off the scene with yellow tape at 9:30am and a bomb disposal unit of the army from Jalalabad Cantonment was called in, said Mossharraf Hossain, officer-in-charge of Sylhet Airport Police Station.

Anamul Haque, proprietor of Anam Enterprise, told The Daily Star that he spotted the “black object” in front of his shop when he opened his store in the morning.

Faisal Mahmud, deputy commissioner (north) of SMP, said no case would be filed as this was in no way a real bomb. He said someone must have left it there to scare people.

However, a general diary would be lodged with Sylhet Airport Police Station, he said.
