Superintendent of Police Babul Akter has returned home after being interrogated by police, his family says.
“He came back a while ago,” his father Abdul Wadud Miah, a former police officer, told the Dhaka Tribune at around 4:45pm on Saturday.
Babul was picked up by police on Friday night. In the morning, Home Minister Asaduzzaman Khan Kamal told the Dhaka Tribune that he was being interrogated.
"He worked in Chittagong and knew many people there. We are questioning him to confirm identities of those arrested over the murder,” he told reporters.
Babul's wife Mahmuda Khanam Mitu was shot and hacked to death in Chittagong on June 5.
He has been living at his father-in-law's Banasree residence with his two children since then. His family said they could not contact him after a DMP team whisked him away from there at around 1am.
Babul was attached to the police headquarters after his transfer and promotion. He was expected to be transferred to Chittagong again to assist in Mitu murder case.
DB Joint Commissioner Abdul Baten said investigators had questioned Babul over the murder but declined to divulge further.
On June 21, police arrested suspects Abu Musa, 45, and Ehteshamul Haque Bhola, 38 – known as Babul's informants.
“Police interrogated Babul about information disclosed by these two,” a police officer said, declining to be named.
