Two unidentified persons on a motorbike opened fire outside Bollywood superstar Salman Khan's residence in Mumbai early Sunday morning, a police official said.
The two persons fired four rounds outside the Galaxy Apartments in Bandra area, where the actor resides, at around 5 am, the official said.
The local police and the crime branch have started a probe into the incident, he said.
A team of forensic science experts also reached the site, the police said.
In March last year, an e-mail threatening Khan was received at his office following which the Mumbai Police registered an FIR against gangsters Lawrence Bishnoi and Goldy Brar.
