New York's attorney general has obtained indictments against 33 people accused of conspiring to distribute heroin and cocaine in northern New York.

According to investigators, wiretaps and surveillance in the year-long probe helped identify four loosely related networks funneling illegal drugs into Potsdam, Edwards, Pierrepont and Stockholm in St. Lawrence County from Yonkers, the Bronx, Syracuse and Leominster, Massachusetts.

Charges range from felony conspiracy and drug trafficking to misdemeanor drug sales.

Authorities say 27 suspects have been arrested and six are still being sought.

They report seizing about two kilograms of heroin, more than five kilograms of cocaine, more than $100,000 in cash, seven handguns, three assault rifles, two shotguns and a rifle.

Attorney General Eric Schneiderman says addictive and deadly heroin has spread even into the most rural counties.
