A Dhaka court today acquitted domestic help Khadiza Akhter Sumi, a co-accused of Oishee Rahman in the case filed for killing a police inspector and his wife in 2013.

She was cleared of the charges as prosecution failed to prove the allegations brought against her, Judge Md Al Mamun of Dhaka Juvenile Court said while passing the order in presence of Sumi.

Soon after the verdict, Sumi broke down in tears and expressed her satisfaction over the verdict.

Earlier on April 22, prosecution and defence lawyers completed their arguments in the case.

In August 2013, Oishee Rahman stabbed dead both of her parents Mahfuzur Rahman, inspector of Special Branch (SB) of Police, and Shapna Rahman at their residence at Chamelibagh in Dhaka.
