Security has been strengthened around industrialist Mukesh Ambani's residence Antilia after the Mumbai police received information that two people were inquiring about it. The CCTV footage around the building is also being checked, the city police said on Monday -- months after the huge security scare when an explosives-laden vehicle was found near the house.
"We received a call from a taxi driver that two people had approached him, asking for the location Mukesh Ambani's residence Antilia," the police told the media on Monday.
"Both men asking for the address had a large bag in their hand, after which the taxi driver immediately informed the Mumbai Police about this," the police told reporters.
The driver's statement is being recorded and a senior officer is monitoring the situation, the police said.
The heightened security for the country's richest man comes after the huge security scare in February, when a Scorpio van laden with explosives was found meters away from his house.
The vehicle was found carrying carried 20 gelatin sticks and a letter addressed to Mukesh and Nita Ambani, the details of which have not been released. The car, found to be stolen, was later traced to a man who was murdered.
The investigation into the matter -- still ongoing -- has uncovered a conspiracy with alleged links to a police officer. Officer Sachin Waze has since been sacked and arrested for links to the murder of the car owner, Mansukh Hiren.
The National Investigation Agency, which took over the probe, also found that Sachin Waze had procured the explosives and parked the SUV near Mukesh Ambani's house, reports said.
The chairman of Reliance Industries, Mr Ambani and his family live in one of the world's most luxurious homes – a 27-storey, 400,000 sq feet building called Antilia in south Mumbai's posh Cumballa Hill area -- since 2012.
