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.
Sex, drugs and Wall Street.
That pretty much sums up Leonardo DiCaprio's new film "The Wolf of Wall Street, " a true life cautionary tale of trader Jordan Belfort, as told through the eyes of Martin Scorsese.
CNN's Nischelle Turner spoke with DiCaprio about the film he also helped produced.
"You know it's been a six year process to get this film off the ground, but I've been obsessed with it in a lot of ways because I feel like it's an accurate reflection of everything that is wrong with the world we live in today," he says.
"The attitude of this character, Jordan Belfort, is directly attributed to the destruction of our economy to, you know, you can attribute this attitude to this darker side of human nature, to everything that has gone wrong in society really. So I wanted to put this character on screen, I really did."

Former supermodel elle macpherson's billionaire husband is at the center of a bombshell lawsuit, CNN's Nischelle Turner reports.
Daria Pastouhkova filed a "wrongful death" suit against Jeffrey Soffer in a Miami federal court for a whopping $100 million.
The suit alleges Soffer caused a helicopter crash that killed her husband, Lance Valdez, in November 2012.
According to the complaint, Soffer was "recklessly flying and controlling" the helicopter as he attempted to land at Baker's Bay golf club in the Bahamas.
Pastouhkova says turbulence suddenly hit when the chopper was less than ten feet off the ground. Soffer then allegedly pulled back too sharply on the controls, causing the helicopter to spin out of control and to rear backwards some 75 feet, causing it to crash violently into the ground.
After the crash, Pastouhkova says Soffer "conspired" with the other passengers and duped her into signing a contract that gave her "$2 million in insurance proceeds..."
An effort, she alleges in the complaint, to conceal that he was piloting the helicopter "for the primary purpose of avoiding his own personal liability."
CNN reached out to Soffer's lawyer for comment– they didn't reply. A rep for Macpherson said the supermodel had "no comment."
