Award-winning south Indian actor Puneeth Rajkumar has died at the age of 46. The beloved star, who has almost 50 film credits to his name, died of a heart attack in Bengaluru on Friday, his manager confirmed. He was reportedly taken to the doctor after complaining of intense fatigue after a gym session and was then rushed to the hospital, where he died. His body is being placed at Sree Kanteerava Stadium, where long queues of fans have formed to pay their respects to the Kannada actor. There has been an outpouring of grief, and offices and shops across Bengaluru reportedly closed on Friday, and police brought in, as there were fears of violence following the actor's sudden death. The actor's older brother, Raghavendra Rajkumar, urged everyone to remain peaceful, and said his family were "in a state of shock". Last rites are being performed on Saturday upon the return of Rajkumar's daughter, Vanditha, from the US, according to <i>The Times of India</i>. Rajkumar, perhaps best known for his award-winning work in<i> Raajakumara</i> and <i>Rana Vikrama</i>, has 48 film credits on IMDb, and played the lead in 29.

Well known for his dancing skills and as a playback singer, Rajkumar appeared in his first film, <i>Bettada Hoovu</i>, with his father, when he was aged 10. Indian Prime Minister Narendra Modi led tributes to the star on social media. "A cruel twist of fate has snatched away from us a prolific and talented actor," the politician wrote on Twitter.
