Philip Seymour Hoffman's flat contained 50 separate packets of heroin.

The actor was tragically found dead with a needle still in his arm on Sunday (02.02.14), and police have recovered numerous packets used to carry heroin and more than 20 used hypodermic needles from the property.

Many of the bags were stamped with 'Ace of Spades' or 'Ace of Hearts', which users say is heroin cut with a powerful pain reliever called fentanyl.

Police remain at the actor's apartment in Greenwich Village, New York City, but an autopsy to confirm the cause of death is to be carried out today (03.02.14).

Other items recovered from the property include a charred spoon and five different medications which police suspect the 'Capote' star didn't have prescriptions for.

Philip was found unconscious at around 11.15am on Sunday by his friend David Bar Katz, who called for assistance.

David had gone to check on the actor after he failed to pick up his children Tallulah, seven, Cooper, ten and Willa, five.

His children live close by to the $10,000 a month apartment he was renting with their mother, Philip's estranged partner Mimi O'Donnell.
