A PIL was filed in the Orissa High Court claiming that the Odisha Police crime branch, which is now investigating the case, is not capable of probing it and will not be able to reveal the truth.
It is, however, not clear whether she was the same woman who had honey-trapped the five accused and allegedly extracted information from them, the police said.
Sources said the lady handler had been calling the accused from different locations after initially establishing a link with them through WhatsApp.
The five ITR employees' seven-day Odisha Police Crime Branch remand ended on Saturday, and they will now be sent to judicial custody.
Earlier in the day, the court of Sub-Divisional Judicial Magistrate at Balasore granted remand of the five, including a staffer and four contractual employees of at ITR for a week.
Meanwhile, the Crime Branch of Police has taken over the charge of investigation from the local police.
The four accused had allegedly communicated classified defence secrets to the foreign agents after they were contacted through various ISD phone numbers.
