Mumbai,  In a major development, the National Investigation Agency (NIA) on Saturday night arrested Mumbai cop Sachin Vaze in connection with the explosive laden SUV found near industrialist Mukesh Ambani's home.

The arrest was made minutes before midnight, after the NIA grilled Vaze for over 12 hours since Saturday morning.

Earlier, a Thane Court had declined to grant interim bail to Vaze and posted his plea for a later date.
