US police track Ledger hoaxer

American police have narrowed down the search for the man who cruelly scammed a host of Hollywood stars by pretending to be the grieving father of late actor Heath Ledger.

An unknown man masquerading as Kim Ledger obtained the contact details of a number of movie stars and has contacted them since Ledger's death, seeking condolences and requesting they attend the 28-year-old's funeral. John Travolta and Tom Cruise are among those reportedly conned.
