"Shah Rukh Khan already has police security. We have now increased the security, going by the increased threat perception," said a police officer.
Police were deployed at his residence in suburban Bandra while the actor is presently not in the country, the officer added.
The additional police security deployment comes two days after film producer Ali Morani allegedly received threats from underworld don Ravi Pujari.
On Sunday, Bollywood producer Morani registered an FIR at Juhu police station claiming that unidentified bike-borne miscreants fired in the air outside his Juhu residence on Saturday night.
Before this, Morani has received extortion calls from a person, who claimed to be underworld don Ravi Pujari.
