PORTLAND — A criminal trial is ongoing in federal court this week for a Brunswick man accused of bank fraud and mail fraud.

Charles Stergios allegedly carried out a scheme in which he floated non-existent cash among accounts that he set up at nine financial institutions. Stergios is accused of using fraudulent checks, wire transfers and empty deposit envelopes to get cash and merchandise in July and August of last year.

The trial opened Monday with Judge George Singal presiding in U.S. District Court. It is expected to conclude Thursday.

Stergios has prior convictions for bank fraud, wire fraud and mail fraud. He gained notoriety in 2005 for hurling a water pitcher at the prosecutor during his sentencing hearing. Stergios was released from prison in June of last year, and was on home confinement during the time of the latest allegations against him.
