NEW YORK (Reuters) – Award-winning actor Philip Seymour Hoffman was found dead in his New York City apartment on Sunday of an apparent drug overdose, according to a New York Police Department source.

The source said Hoffman was found dead after a 911 emergency call from a friend of the actor. The source gave no further details.

The New York Times, citing a law enforcement official, said investigators found a syringe in Hoffman’s arm and an envelope containing what was believed to be heroin.

Hoffman, 46, won the Academy Award for Best Actor for the 2005 biographical film “Capote,” and received three Academy Award nominations as Best Supporting Actor.
