Bollywood actor Emraan Hashmi has lately rejected an offer to play the 'Bikini Killer' Charles Shobhraj even though he is better known as 'serial kisser' for locking lips with Bollywood babes onscreen.

Director Prawal Raman is planning to make a film on the serial killer Shobhraj and he offered the lead role to Emraan. But the actor, who is on a high with the success of his latest release Once Upon A Time in Mumbaai in which he has recently played a gangster, showed his unwillingness to play another negative role consecutively.

Prawal has earlier directed the movies such as Gayab, Loot, Darna Mana Hai and Zabardast.

According to a source close to the actor, "Emraan is not interested to play the same kind of role once again as he does not want to be a typecast. He will definitely do such kind of negative role in future but not right now."

Currently, Shobhraj the accused in the murder case of an American tourist in 1975 is serving a lifelong sentence in Nepal. The 66-year-old is believed to be a psychopath, who has allegedly murdered 12 people all over Asia in the 1970s. Thus he has earned the moniker of 'serpent' and 'bikini killer'.
