The sign on Dr. Felix Lanting's front door reads "closed permanently due to a family emergency."
Earlier Tuesday, Federal agents lugged boxes of evidence from the Hunter Avenue home which the doctor also uses as his office.
The 83-year-old was arrested for allegedly distributing lots of Oxycodone.
One neighbor didn't want to be identified but told Eyewitness News everyone knew what was going on in Grant City, Staten Island.
"It's ridiculous. Now that he's down it's going to be much better because he really was the supplier for Staten Island," said the neighbor.
Prosecutors allege in court papers that Lanting handed out about 3,000 prescriptions of Oxycodone over the last seven months, making for an average of 15 per day, seven days a week.
Officials say nearly 500 customers were under 30 years old.
And the prescriptions of 180 or 240 Oxycontin pills sold for $200.
Business was so good that Lanting allegely hired "goons" and "bouncers" to control his front door.
Some long time neighbors can't believe the allegations.
"All this commotion. I don't know anything about it. The only thing i know is that he was a good doctor," said Elvira Demasi.
If convicted the suspect could face 20 years behind bars.
