A threatening call to Bollywood star Shah Rukh Khan triggered a flurry of police activity Thursday, with cops from Mumbai and Chhattisgarh's Raipur (the hometown of the man accused of calling in the threat and demanding Rs 50 lakh) announcing separate investigations into the incident. The man accused of making the threat is Mohammad Faizan Khan, a lawyer. But there is a twist. Mr Khan has said his mobile phone - which was used to make the threatening call on Tuesday - was stolen last week. He also said he filed a police case to that effect on Saturday. Mr Khan has now been summoned to join the Mumbai Police's investigation. Earlier, a Chhattisgarh cop told news agency ANI colleagues from Mumbai landed up in his jurisdiction this morning to inform him of a case registered in Bandra Police Station in that city. "Today Mumbai Police came to Pandri Police Station to inform us a crime had been registered in Bandra Police Station, where Shah Rukh Khan was threatened and money was demanded."
