George Clooney Gives Moving Philip Seymour Hoffman Tribute As Four Are Arrested In Connection With His Death

At the premiere of his latest film Tuesday night, George Clooney payed tribute to his former co-star and friend Philip Seymour Hoffman in the wake of the actor's death Sunday morning.

"Phil was a good friend to a lot of us in this community. And it's a community. And it makes it very difficult to be here 48 hours in this town after he died," admits the 52-year-old, who directed and co-starred with Hoffman in 2011's "The Ides of March."

"I think everybody here is putting on a brave face to get through this because it's a pretty traumatic time," Clooney continued. "We're going to miss him a lot. And it's senseless in a lot of ways so it's hard to do. We miss him."

Hoffman died of an apparent drug overdose at his NYC home where police found nearly 70 bags of heroin and a needle still stuck in the actor's arm.

As Clooney and his co-stars were celebrating their new film "The Monuments Men," police were arresting four individuals in connection with the drugs found in Hoffman's apartment.

According to reports, three men, two in their 50s and one in his 20s, and a woman in her 20s have been arrested and brought in for questioning. Police raided a Chinatown apartment after receiving a tip that the drugs supplied to Hoffman came from the building.

Though it is still unclear what combination of drugs killed the actor, the autopsy results are expected to be released today.
