An Augusta man pleaded not guilty Wednesday to the June 23 robbery of the Hallowell branch of the Bank of Maine.

John Cecil Slater, 66, was arraigned by Magistrate Judge John Nivison in U.S. District Court in Bangor on an indictment charging Slater with bank robbery.

A conviction on the federal bank robbery charge carries a maximum prison term of 20 years.

If Slater is convicted, the government also is seeking forfeiture of a 2002 Yamaha motorcycle “derived from proceeds traceable to the violation.” The indictment was handed up by a federal grand jury on Aug. 13.

A separate order by Nivison on Wednesday says a trial in the case is set for Oct. 6 before U.S. District Court Chief Judge John A. Woodcock Jr.

Police identified Slater as the robbery suspect after viewing surveillance videos and issued a plea for the public’s help in locating him. He was described as armed and dangerous.

Slater was arrested by FBI agents July 9 in Twin Mountain, New Hampshire, and has been in custody since.

Documents unsealed after Slater’s arrest show investigators found paper similar to that used to write the robbery note in Slater’s apartment.

An affidavit filed by FBI Special Agent Glenn D. Barnes says the robber fled with $15,000 in $100 bills.
