VERNON — A man who fled to South Korea during an investigation of a fraudulent prescription drug sales ring is in custody after he was arrested while trying to re-enter the United States, police said Saturday.

Bong K. Ahn, 29, is the last of seven people who have been charged in a conspiracy to fraudulently obtain and sell prescription narcotics including Roxicodone, in an investigation that was launched in 2009 by Vernon Police and the East Central Narcotics Task Force. The two leaders of the group, Anthony "Tony" Navarro and Mathieu Fauteux, have been convicted and are serving prison sentences, Vernon Police said.

Ahn was detained at a New York City airport by Customs officials and was extradited by Vernon Police. He was charged with three counts each of possession of narcotics, sale of narcotics, obtaining drugs by fraud, second-degree forgery, conspiracy in the possession of narcotics, conspiracy in the sale of narcotics, conspiracy in the obtaining drugs by fraud, and conspiracy of forgery, with a total surety bond of $45,000.

Ahn, who had a listed address in Suffield until 2010, was being held Saturday in lieu of bail. Police said they did not anticipate further arrests in the investigation.
