Indian police have advised prominent Bollywood actors to avoid large gatherings, public places and crowded areas after actor Tiger Shroff was shot and injured in Mumbai last month, prompting renewed security concerns surrounding film personalities. Mumbai Police issued the advisory as a precautionary measure amid concerns over the safety of Bollywood stars in the city, local media reported on Tuesday, quoting an unnamed senior police officer. The Mumbai Police Commissioner's office did not respond to a Reuters request for comment. Shroff was shot and injured in October when three men opened fire on his car as he was leaving a football ground in Mumbai, India's financial and entertainment capital. Indian media said his driver and a bystander also sustained injuries. A report by Indian news website The Hindu quoted an official as saying that the incident took place around 7pm in Johu. The three suspected shooters were arrested within days, while eight others allegedly linked to the conspiracy were subsequently detained, according to local media reports citing police. Police are investigating whether the attack was connected to a criminal gang allegedly associated with previous attacks targeting Bollywood personalities, the reports said. The incident has prompted a wider security reassessment by police and private security teams responsible for protecting film stars. Security measures have become more visible during public appearances by prominent actors since the shooting. Veteran actor Amitabh Bachchan, for instance, has been greeting fans outside his Mumbai residence from behind protective glass, according to images circulated on social media and carried by local media. Bollywood has faced threats from organised crime groups for more than three decades, including shootings, extortion demands and intimidation targeting actors and other industry figures.
