Earlier, the court had stayed a trial court's order which had allowed Tyagi to travel abroad.
Justice I. S. Mehta has clearly said that Tyagi is facing trial in the case and also getting special treatment, adding that he may tamper the ongoing probe.
In December 2015, Tyagi was granted bail on Rs. two lakh security.
Hearing the matter, the court directed Tyagi not to leave Delhi-NCR and not to tamper with evidence.
The Central Bureau of Investigation (CBI) counsel had earlier on December 23 last year requested the court not to disclose evidences to anyone, while stating that if the evidence gathered will be disclosed then there would be implications on future investigation into the case.
Tyagi has been accused of influencing the deal in favour of Agusta Westland during his tenure as the IAF chief. He has, however, repeatedly denied the allegations.
