STAMFORD - A major drug bust made in Stamford yesterday is raising concerns over prescription pill addiction in southwestern Connecticut.

According to investigators, the initial arrest was made by a Stamford detective in April. They say a man, whose name is not being released, was trafficking oxycodone, which led to the arrest of 20 more people.

Police say the man is accused of bringing the highly addictive painkiller into the area several times a week, potentially landing them in the hands of young adults.

A Stamford pain management specialist, Dr. Vincent Carlesi, says oxycodone abuse is partially responsible for a rise in prescription drug overdoses. Authorities say the latest arrests are part of the crackdown on what they view as a growing, very serious problem.
