Four people have been arrested in connection to the death of Philip Seymour Hoffman, two days after the Oscar-winning actor was found dead in his apartment of an apparent drug overdose.

The night law-enforcement officials busted four people, who are believed to have supplied the heroin that killed the 46-year-old actor, reported New York Post online. Three men two in their 50s and one in his 20s and a woman in her 20s had been detained and were being questioned. They were reportedly arrested in a Chinatown apartment on Mott Street after police received a tip that the drugs found in Hoffman's apartment came from the Chinatown building.

Police reportedly found 350 glassine envelopes containing a substance believed to be heroin. However, the Hollywood Reporter says that there is no truth to reports that four drug dealers were busted in connection with the actor's apparent drug overdose. The New York Police Department has also revealed that heroin recovered at Hoffman's apartment has tested negative for powerful additive, fentanyl.

A friend found the 'Capote' actor dead inside his Manhattan apartment on Sunday with a syringe in his arm. Investigators recovered more than 50 bags of heroin, along with syringes, a charred spoon and various prescription medications, including a blood pressure drug and a muscle relaxant, law enforcement officials said.

While official toxicology results are forthcoming they will likely be released next month preliminary tests of the heroin showed no traces of fentanyl. Investigators have determined that Hoffman made six ATM transactions for a total of USD 1,200 inside a supermarket near his home the day before his death.
