AUGUSTA — The part-owner and general manager of a well-known Kennebunk restaurant, Bartley’s Dockside, has been sentenced to three years in prison with all but nine months suspended for tax evasion and unemployment fraud.

Brian Bartley, 59, of Kennebunkport, was also sentenced in York County Superior Court to three years of probation and to pay $87,365 for money stolen, income tax evaded and recent restaurant taxes he failed to pay during the criminal prosecution, according to the Attorney General’s Office.

Bartley pleaded guilty to a 20-count indictment that included charges of theft of sales tax, income tax evasion, theft by deception and unemployment fraud. The investigation covered the period from 2003 to 2007.

The Attorney General’s Office said Bartley regularly stole a portion of sales taxes for personal use and used the restaurant as a vehicle for tax evasion by having it pay tens of thousands of dollars in personal expenses, including mortgage and car payments, home utility bills and personal credit card expenses. The office said Bartley also fraudulently applied for and received thousands of dollars in unemployment compensation.

Bartley and his father, James, were convicted of similiar offenses in 1991. Each served three months in jail. The state collected $200,000 in restitution for which they and the restaurant were responsible.
