The vehicle with explosives found near industrialist Mukesh Ambani's residence in south Mumbai had been stolen last week, and a letter found inside said it was only a "glimpse" of things to come, police said on Friday.
A Scorpio with gelatin sticks was found parked on Carmichael Road near 'Antilia', the multi-storey residence of Ambani, the chairman of Reliance Industries, on Thursday evening.
The registration number on the vehicle's number plate was the same as that of an SUV in Ambani's security detail, police had said.
"The owner of the vehicle, Hiren Mansukh, visited the police commissioner's office in south Mumbai this afternoon after he saw visuals of the SUV found near Ambani's house, which was similar to his vehicle," a police official said.
