LONGWOOD - A joint undercover operation by the FBI and NYPD has led to more than 10 drug-related arrests.

According to federal attorneys, 13 suspects were arrested and indicted Thursday for violating U.S. drug laws, specifically those pertaining to distribution. 

Authorities say the suspects sold 280 grams of crack and one kilogram of heroin to undercover cops from June 2012 until this month. In September alone, they sold 40 grams of heroin for $2,500.

The indictment also says the suspects will have to relinquish all property relating to their drug sales.
