Hoffman dead of apparent drug overdose -- police

NEW YORK, Feb. 2 (UPI) -- U.S. actor Philip Seymour Hoffman was found dead Sunday of an apparent drug overdose in his New York apartment, police sources told CNN.

The Oscar-winning Hoffman, 46, was found in the bathroom of the fourth-floor Manhattan apartment, the sources told CNN.

Investigators found a syringe in his arm and an envelope containing what may be heroin, an unnamed official told the New York Times.

"It's pretty apparent that it was an overdose," the official told the newspaper. "The syringe was in his arm."

Hoffman won the Academy Award for Best Actor for 2005's "Capote," portraying writer Truman Capote.

The Times said Hoffman had undergone treatment for drug addiction in the past, but said he had fallen "off the wagon" last year after being sober for 23 years.
