AUGUSTA — The Maine Office of Securities is seeking information from Maine residents who have invested in, or been approached about investing in the treasure hunting activities of Greg Brooks of Gorham.

According to reports, Brooks has been unsuccessfully hunting for underwater treasure from Maine to the Caribbean since the mid-1980s.

The state securities agency’s current investigation includes Brooks and his Portland-based activities involving Sea Hunters L.P., Sea Hunters 2 L.P. and Deep Sea Hunters L.P.

“Potential investors may have been contacted directly by Mr. Brooks or his representatives or attended a presentation outlining his undersea recovery efforts,” said Maine Securities Administrator Judith Shaw in the press release seeking the public’s help.

Shaw is asking people with information to contact the Maine Department of Professional and Financial Regulation, Office of Securities, by calling 1-877-624-8551.
