Why did they kill my son?

The three-year-old boy whose body was recovered from a rooftop water tank in the capital's Shyampur area on Tuesday was kidnapped by a masked man from Gazipur on Saturday.

The victim was Nihad Islam, only son of Hanif Ali and Nargis Begum, who are workers of a garment factory in the district.

Hanif went to Dhaka Medical College morgue yesterday afternoon after seeing the news of the recovery of a minor boy's body.

He identified the swollen and decomposed body as that of his son's when he saw a key and a small bell tied with a string around the boy's waist.

Talking to The Daily Star, Hanif said Nihad was abducted after the boy went with his mother to her garment factory in Board Bazar area in Gazipur.

A CCTV camera installed in front of the factory showed a masked man taking him away, the father said. The parents filed a complaint with the local police station in this regard.

"My son was killed brutally. We are very poor and we do not have any known enemies. Why did they kill my son? We want justice," he said.

Hanif said no one called him demanding ransom for the return of his child.

Sub-inspector Mahbubur Rahman of Shyampur Police Station said the body was handed over to family members after an autopsy at DMCH.

Police are yet to arrest anyone in this regard, he added.

Pradip Biswas, a forensic doctor at DMCH who conducted the autopsy, said no marks of torture were visible as the body was already decomposed.

"We sent the rectal swab, viscera and other samples for different tests. We will be able to determine the cause of his death upon receiving the reports," he said.
