Update: Actor Heath Ledger has been found dead in a Manhattan apartment.
Ledger was 28 years old. Authorities believe his death may be drug-related.
An NYPD spokesman says Ledger had an appointment for a massage at the apartment. A housekeeper who went to let him know the masseuse had arrived found him dead.
The Australian-born actor was nominated for an Oscar for his role in "Brokeback Mountain." He was to appear as the Joker this year in "The Dark Night," a sequel to 2005's "Batman Begins."
