The wharf manager at Spruce Head Co-op, located on Spruce Head Island, has been arrested and charged with Class B theft in connection with business dealings at the co-op, according to police.

On Wednesday, Oct. 3, the Knox County Sheriff's Office executed three search warrants as part of an investigation of Robert Thompson, 51, of St. George. Thompson was arrested for Class B theft that same day, according to a news release from the Knox County Sheriff's Office.

A fourth warrant was executed on Oct. 4. The search warrants were at Thompson’s residence in St. George, his camp in Rockwood, at a business known as JP’s Shellfish in Eliot and a local bank.

The investigation has gone on for months, led by the Criminal Investigation Division of the Knox County Sheriff’s Office and assisted by the Maine Marine Patrol, U.S. Coast Guard, National Marine Fisheries Service, and the Internal Revenue Service. All were part of the execution of the warrants.

Evidence was obtained, much of it in document form, at all four locations. It will take many days to sort through all the evidence. The investigation continues and may reveal additional charges, according to the news release. It is unknown at this time if others will be charged.

Thompson’s first appearance in court is scheduled for Dec. 26 at the Knox County Superior Court. Thompson was released on bail from the Knox County Jail Oct. 3 after providing $100,000 surety bond.

As a condition of release, Thompson is to have no contact with employees at either company and not to return to Spruce Head Co-op, according to court records.
