The Detective Branch (DB) of police yesterday detained another suspect in connection with the killing of tailor Nikhil Chandra Joardar in Tangail's Gopalpur upazila.

He is Goutam Rudhra, ex-husband of Nikhil's niece Swarna Joardar.

A Tangail DB police team detained Goutam at his home in the capital's Uttara early yesterday, said Mahfijur Rehman Ghulam, officer-in-charge of the Tangail DB police.

Goutam married Swarna two years ago, and they separated a year ago.

“We detained Goutam for interrogation in the killing incident as he had been issuing death threats to Nikhil since the divorce,” the DB official said, quoting Nikhil's family.

Nikhil, 50, was hacked to death by unidentified criminals on Saturday near his shop at Dubail Bazar in Gopalpur municipality area.

On Sunday, Gopalpur police detained three people -- Rafiqul Islam Badsha, secretary of Gopalpur upazila unit Jamaat-e-Islami, Maulana Aminul Islam, principal of Alamnagar Madrasa, and BNP activist Jhantu Miah -- for their alleged involvement in the murder.

Aminul had filed a case against Nikhil for “derogatory comments” about Prophet Muhammad (pbuh) on May 2, 2012.

The DB police on Monday showed the three arrested in the two cases filed for Nikhil's murder and produced them before the Senior Judicial Magistrate's Court in Tangail with a remand prayer.

The court placed the suspects on  six-day remand each.
