Mumbai, Jan. 21 :     Alleged Abu Salem assassins today fired at actor-turned-hit director Rakesh Roshan outside his Santa Cruz office. The filmmaker, celebrating the mega-success of his latest blockbuster - Kaho Naa...Pyaar Hai, launching son Hrithik - survived the attempt and was admitted to hospital with wounds on his arm. Sources said two assailants struck as Roshan was getting into his black Mercedes outside his office at Mayur building around 6.30 pm. They fired six rounds, of which two bullets hit the actor on his left arm, while another struck his shoulders. Roshan's driver, who was not injured, shoved him inside the car and sped away to the nearby Santa Cruz police station. The police later took the actor to Nanavati hospital near his Juhu residence, behind Amitabh Bachchan's bungalow. Hospital sources said Roshan was operated upon by Sharad Pandey. His family members have been allowed to meet him. Though he is out of danger, Roshan has been kept in the intensive cardiac care unit as he is a heart patient. Kaho Naa...Pyaar Hai opened to 100 per cent collections last week, dispelling much of the gloom cast following the flops of big-budget films like Mela and Bulandi. Police sources have yet to confirm if Roshan had received extortion calls from the underworld after the apparent success of his film. A senior officer at the Santa Cruz police station said the director had received an extortion threat in the past following which he was given security cover, which was withdrawn after some time. Today's incident is the latest in the string of attacks on Bollywood producers. Music tycoon Gulshan Kumar was shot dead in August 1997, also by gangsters allegedly belonging to the Abu Salem gang. Composer Nadeem is an accused in the case. A few months later, top producer Mukesh Duggal was gunned down for refusing to honour commitments made to the underworld, which is believed to have financed his films. Rajiv Rai, director of mega-hits such as Tridev and Gupt, had also received extortion threats and was provided police protection. But the assailants did manage to breach the security ring and fire at him. Rai, who was saved by his guards, left the country soon after and returned a few months ago. The underworld began targeting Bollywood producers after the property business crashed in the mid-nineties and the traditional source of their extortion income dried up. Roshan, a not-so-successful actor in the seventies and early eighties, produced and directed a string of hits, including Khud Garz, Khoon Bhari Maang and Karan Arjun. The director had left home for office in the afternoon after an interview session at which Hrithik was present.
