The court also allowed the Central Bureau of Investigation (CBI) to interrogate Sachin Waze in NIA custody in connection with its preliminary enquiry into the allegations of corruption levelled by senior police officer Param Bir Singh against former Maharashtra home minister Anil Deshmukh.
The court directed CBI to coordinate the timings of the interrogation.
On March 13, Waze was arrested by the NIA in connection with the probe into the recovery of explosives from an SUV found parked near businessman Mukesh Ambani’s south Mumbai residence on February 25.

Waze was today produced before special NIA court judge P R Sitre, who extended his custody to the probe agency till April 9.
The NIA had sought the extension of Waze’s remand for further probe into the case.
Two other accused in the case — suspended police constable Vinayak Shinde and cricket bookie Naresh Gor — were remanded to 14-day judicial custody by the court.
A Scorpio with explosives was found near Ambani’s residence in south Mumbai on February 25.
