But its red alert for Salman Khan as Mumbai Police launches a probe, an official said on Monday. The phone call was made to the city’s Police Control Room on February 16, police said. Police suspected it was a hoax call and launched a probe though no case has been filed yet. Police has managed to locate the place from where the call was made. Not willing to take chances, cops have decided to review the 50-year-old actor’s security.
