The CBI on Wednesday approached a special NIA court here seeking permission to question suspended police officer Sachin Waze in connection with its preliminary enquiry into the allegations of corruption against former Maharashtra Home Minister Anil Deshmukh.

Waze was arrested on March 13 in the case of an explosives-laden SUV found near industrialist Mukesh Ambani's house in south Mumbai on February 25 and the subsequent death of Thane-based businessman Mansukh Hiran.
