She communicated with the murderers and held meetings with the masterminds behind the fatal attack on Rifat, police said when she was being quizzed in custody on Thursday.
On Friday afternoon, three days into her five-day remand, police took her to court where she gave the statement under Section 164 of the Code of Criminal Procedure or CrPC, Barguna Sadar Police Station Inspector Humayun Kabir, who is investigating the case, said.
Such statements recorded by the court in the course of investigation can be used as evidence during trial.
Inspector Humayun could not give details of Minny’s statement to the court.
The judge, Barguna Senior Judicial Magistrate Md Sirajul Islam Gazi, ordered her into jail in the evening after recording the statement.
Barguna Superintendent of Police Md Maruf Hossain on Thursday said police found evidence of her involvement in the murder conspiracy.
Rifat, 23, died after a group of assailants hacked him after beating him up on College Road in the town on June 26 when he went to pick up his wife from college.
A video of Minny trying to save her husband from the attackers went viral on social media, creating an outrage.
Police killed the key suspect, Sabbir Ahmed alias Nayon Bond, in a so-called gunfight on July 2.
