Bollywood actor Salman Khan has once again received a threatening phone call from a person claiming to be ‘Roki Bhai’ from Rajasthan's Jodhpur. The death threat call was made on Monday night, as reported by sources. The caller had warned Salman Khan of his intention to kill him on April 30. The Mumbai police and Crime Branch officials are currently trying to trace the caller's location. This isn't the first time the Bollywood star has been threatened. Earlier, Salman Khan had received a threat via email, following which his security was increased. The email was allegedly sent by gangster Goldy Brar, who was involved in Congress leader and Punjabi singer Sidhu Moose Wala's murder last year in May. To ensure his safety, Salman Khan recently purchased a new white Nissan Patrol, a seven-seater SUV with bulletproof capabilities, after receiving several threats. The authorities are taking the matter seriously and are working towards ensuring the safety of the actor.
