Zarina Bibi had on June 30 filed a petition in the Calcutta High Court seeking a CBI inquiry into the killing of her sons claiming lack of confidence in the police.
"We shall come again and take all required steps to get justice. We shall take them to the President of India if required," Chowdhury added.
