Police yesterday were allowed three days to interrogate Jannatul Ferdaus Nila, the councillor of wards 4, 5 and 6 in Narayanganj City Corporation, in a murder case filed last year.
Siddhirganj police OC Alauddin said they were given the permission upon a seven-day remand petition filed with the court of Chief Judicial Magistrate Jabid Hossain.
He said they had arrested Nila on Sunday night related to a 2013 murder case, not in the seven-murder case.
Nila was picked up on May 18 and interrogated over the seven murder case for three hours.
Alauddin said they had arrested Nila based on confessions made by the accused arrested in the case filed over the murder of a youth named Jewel.
Police recovered the body of Jewel with a severed head on October 27 last year. His identity was confirmed around a month later.
A case was filed later and as such, criminals, who had alleged link in the murder, were also arrested.
