Security tightened around Mukesh Ambani's house after cabbie calls cop over security threat
According to reports, the CCTV footage around the building is also being monitored by the police.
This comes 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 of 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.
They have recorded the driver's statement and a senior officer is monitoring the case.
In February this year, a vehicle was found loaded with 20 gelatin sticks and a threat letter to the Reliance Industries chief Mukesh Ambani's family.
Later, the owner of the vehicle was found murdered.
The investigation into the case is still continuing and 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.
Currently, the National Investigation Agency (NIA) is conducting the probe.
