Indian police have advised prominent Bollywood actors to skip large gatherings, avoid public places and stay away from fans in crowded areas, Indian media reported on Tuesday.

Mumbai Police issued the advisory as a precaution because of renewed security concerns about the security if film stars in the city, the reports said. They cited an unnamed senior police officer.

The advisory follows the October 18 attack on actor Tiger Shroff in Mumbai’s Juhu area, where three men on motorcycles opened fire on his car. Police said Shroff escaped unhurt, but his driver and an autorickshaw driver suffered injuries. A gang linked to Lawrence Bishnoi claimed responsibility.

Police arrested the three suspected shooters within days and later detained eight others allegedly linked to the conspiracy, local media reported. Investigators are checking whether the attack connects to a criminal gang that has targeted Bollywood figures before.

The incident prompted police and actors’ private security teams to reassess protection for film personalities, local media said.
