Police had brought her to the court at noon on Saturday. She made her deposition before Metropolitan Magistrate Anwar Sadat at his chamber.
Court’s General Recording Officer Sub-Inspector Abdul Gaffar told bdnews24.com that Oishee gave her confessional statement in the case filed over her parents’ murder.
Housemaid Khadiza Khatun Sumi and Oishee’s friend Mizanur Rahman Rony were also presented before the court.
Sumi also gave her statement to Magistrate Sadat, Gaffar said.
Meanwhile, after presenting him before the court, police pleaded for a 10-day remand for Rony for further questioning. The court of Magistrate Asaduzzaman Nur was to hear the plea on Saturday.
A Dhaka court had sent the trio to five days police remand on August 18. Different quarters have already criticised the court decision to send both ‘minors’ Oishee and Sumi to police remand.
Police’s SB Inspector Mahfuz and his wife Swapna were found brutally murdered in a locked bathroom in their Chamelibagh residence on Aug 16.
The post-mortem report said they died of stab wounds inflicted by ‘multiple killers’ who were believed to be amateurs.
Prior to that, Police suspected Oishee’s involvement in the couple’s murder as she could not be traced before Aug 17. However, she surrendered the next day. Police later arrested Rony and Sumi.
Police in its remand plea had said Oishee had killed her parents with the help of her drug-addict friends. She needs to be questioned to ascertain the identities of those friends and the motive, the plea had said.
Officers involved in the interrogation had also claimed Oishee had admitted her involvement in the killings.
But her uncle, Mahfuz’s brother, Moshiur Rahman Rubel suspects that there might be another 'mystery' behind the gruesome double murder.
Meanwhile, questions were raised about Oishee’s age when she was being quizzed in police custody. Facing criticisms, police took Oishee to the Dhaka Medical College and Hospital on Aug 21 to ascertain her age through medical tests. The report is yet to come.
According to documents at the Oxford International School, where she is an ‘O-level’ student, Oishee is yet to be 18 years old. Records there show Aug 17, 1996 as her date of birth.
National Human Rights Commission (NHRC) Chairman Mizanur Rahman along with various human rights organisations criticised the detention and the remand of two minors – Oishee and Sumi-- saying the moves had violated the Children Act.
