Four people thought to be connected to the drugs found in late actor Philip Seymour Hoffman's apartment were arrested late Tuesday night, law enforcement officials told CNN.
During the raid that yielded the arrest of the three men and one woman, police recovered 350 glassine-type bags of what is believed to be heroin, the officials said.
No additional information was released.
When police were called to Hoffman's fourth-floor Manhattan apartment Sunday, they found the actor lying on the bathroom floor with a syringe in his left arm. He was wearing shorts and a T-shirt, his eyeglasses still resting on his head, according to law enforcement sources familiar with the inquiry.
Investigators discovered close to 50 envelopes of what they believed was heroin in the apartment, the law enforcement sources said. They also found used syringes, prescription drugs and empty glassine-type bags, the sources said.
No fentanyl found
Preliminary tests Tuesday showed the heroin recovered from the apartment does not contain fentanyl, a law enforcement official told CNN. More testing will be done.
Fentanyl is a powerful narcotic used to treat cancer patients' pain.
Last week, Maryland officials said heroin tainted with fentanyl had claimed at least 37 lives since September. And last month, at least 22 people died after using heroin mixed with fentanyl in western Pennsylvania.
While results of an autopsy will definitively reveal exactly how Hoffman, 46, died, the role heroin may or may not have played is a key part of the investigation.
Police are trying to piece together the actor's movements last weekend as they look for anyone who might be linked to the drugs that apparently killed him.
On Tuesday, a law enforcement source told CNN that the night before Hoffman died, he withdrew $1,200 from a grocery store ATM near his apartment.
Hoffman got the money in six transactions Saturday night, according to the source.
A witness told investigators he saw the Oscar-winning actor talking to two men wearing messengers bags about 8 p.m.
Police are also reviewing surveillance video, including one of a restaurant where Hoffman had brunch Saturday morning with two people.
'I'm a heroin addict'
In a 2011 interview with "60 Minutes," Hoffman discussed his past struggles with drug and alcohol addiction.
"Anything I could get my hands on, I liked it all," he said.
Fear, Hoffman said, made him sober up.
"You get panicked. ... I was 22 and I got panicked for my life, it really was, it was just that," he said. "And I always think, 'God, I have so much empathy for these young actors that are 19 and all of a sudden are beautiful and famous and rich.' I'm like, 'Oh my God. I'd be dead.'"
But last year, Hoffman said he'd fallen off the wagon, started taking prescription pills and slipped into snorting heroin, according to TMZ.
Magazine writer John Arundel said he met the actor at the Sundance Film festival in Utah two weeks before his death.
"I said, 'What do you do? And at that point, he took off his hat and he said, 'I'm a heroin addict,' " Arundel said.
"Didn't look like he was (joking). Seemed like he was having one of those 'coming to God' moments- where it just stuck him as, 'this is the revelatory moment.'"
But actor George Clooney said he had dinner with him a few months ago, and he seemed fine.
"I have to say he seemed in pretty good shape," Clooney said. "I mean, there's no way to explain it."
Dim the lights
Family and close friends of the actor will hold a private funeral service in New York. Plans are also under way for a memorial service later this month. No information on the dates was available.
On Wednesday night, the famed Broadway theater district will dim its marquees for one minute at 7:45 p.m. in Hoffman's memory.
Oscar-winning actor Philip Seymour Hoffman was found dead in his Manhattan apartment Sunday of an apparent drug overdose, law enforcement sources said.
Police said Hoffman, 46, was found on the bathroom floor and pronounced dead at the scene. Investigators found two bags of what is believed to be heroin inside the fourth-floor apartment, law enforcement officials said.
"We are devastated by the loss of our beloved Phil and appreciate the outpouring of love and support we have received from everyone. This is a tragic and sudden loss and we ask that you respect our privacy during this time of grieving," Hoffman's family said in a statement. "Please keep Phil in your thoughts and prayers."
Hoffman was last seen alive at 8 p.m. Saturday, a law enforcement official said. He was expected to get his children on Sunday, but didn't show up, the official said.Playwright David Katz and another person went to the apartment and found him dead, the official said.
A needle was in the actor's left arm, and eight empty glassine-type bags that usually contain heroin were found in the apartment, law enforcement sources told CNN.
The bags were stamped with "Ace of Hearts" and "Ace of Spades" - street names for the heroin, the sources said.

Two passengers on the Metro-North train that derailed in New York have filed a notice of claim against the commuter railroad, an initial step in a lawsuit seeking damages in connection with the accident.
Four people died and 67 others were injured in the crash. "The families of those killed in Sunday's derailment in the Bronx began laying their loved ones to rest today," reports CNN's Nic Robertson.
The NTSB, meanwhile, has booted the rail union from its investigation into the derailment for violating confidentiality rules.
The agency made the announcement late Tuesday night, hours after a union representative told CNN the train engineer apparently "was nodding off and caught himself too late" before the accident.
In its announcement, the NTSB specifically cited those comments as the violation.
Anthony Bottalico, the union representative, told CNN that engineer William Rockefeller Jr. recognizes his responsibility in the incident.
"I think most people are leaning towards human error," Bottalico said.
Rockefeller's lawyer, Jeffrey Chartier, characterized what happened as "highway hypnosis." He said his client had had a full night's sleep before the crash and had no disciplinary record.
On Wednesday, Chartier said his client never blamed the accident on faulty brakes, disputing earlier statements attributed to Rockefeller.
"Prosecutors are not saying whether it could lead to criminal charges, waiting for the NTSB investigation," Robertson says.
