NUTLEY - A yearlong investigation into a drug ring ended with a raid on a doctor's office this morning.

Several agents from the Drug Enforcement Administration (DEA) raided the offices of Doctor Michael Durante in Nutley.

Authorities say Durante and 10 others were arrested, including a retired Newark police officer. Federal officials say the doctor allegedly wrote unnecessary prescriptions for the drug Oxycodone, which would be filled and sold on the street.
