All it requires is a phone call from Dubai or Malaysia for a businessman or a film producer or actor to panic. Ever since Dawood has been holed up in a Karachi hideout, his brother Anees or henchman Abu Salem conduct operations. The modus operandi is simple.

Call him," is a typical one-liner; or "get in touch with Nana" if the gang in question is Chotta Rajan's.
