An Augusta man was arrested on a federal warrant charging him with conspiracy to distribute heroin and cocaine base.

Jason Folkner, also known as “Crazy,” joins 10 others who were arrested recently on an indictment charging them with being involved in the same conspiracy.

Records at U.S. District Court in Bangor show that Folkner, whose age is listed as 41, was arrested Sunday in Augusta.

The prosecutor, Assistant U.S. Attorney Joel B. Casey, is seeking to have Folkner held without bail, saying that there is probable cause to believe he committed a crime that carries a term of imprisonment of more than 10 years.

Magistrate Judge John Nivison ordered Folkner held temporarily until a hearing on that issue, which is now set for July 7 in Bangor.

The indictment was handed up by a federal grand jury May 17 but sealed until Folkner’s arrest.

Attorney Jeffrey M. Silverstein was appointed to represent Folkner, who pleaded not guilty Monday at his arraignment.

All the defendants face charges of conspiracy to distribute and to possess with intent to distribute controlled substances, which are heroin, fentanyl and cocaine base from June 2015 to March 2017. Several are charged with possession with intent to distribute controlled substances and maintaining drug-involved premises from June 14, 2015, to March 9, 2017, in central Maine.
