Nitesh and Baljeet Singh Shehrawat were produced before Metropolitan Magistrate Prashant Sharma after expiry of their six-day police custody and the investigating officer moved an application seeking their remand for further custodial interrogation saying they needed to be confronted with various facts that have emerged during the probe.
While the Delhi Police had sought extension of their custody by six days, the court extended their remand by three days till April 19.
Police said they also needed to ascertain the source of money which was involved in the crime.
They said a letter has emerged during the probe and it could be vital in the case. They, however, said the contents of the letter cannot be disclosed in the open court.
Seeking extension of police custody of Nitesh and Shehrawat, the police said the duo are yet to be confronted with the communication they had entered into using Internet applications.
