Arrested Mumbai cop Sachin Vaze met Mansukh Hiran on February 17, the day the Thane businessman's Mahindra Scorpio SUV was stolen, sources have said. A week later, the car was found on the city's Carmichael Road, near industrialist Mukesh Ambani's residence, laden with explosives and a threat letter to the Reliance Industries chief's family. The National Investigation Agency (NIA) and the Maharashtra Anti-Terrorism Squad (ATS), which are probing three cases related to the incident, have now found CCTV footage of the two together on that day in the Fort area of the city, they said.
