Oak Bluffs’ new police officer, Seth Harlow, got a glowing review this week from police chief Erik Blake, described as having “an amazing ability to assimilate in any group, a maturity level that’s unmatched.”

Chief Blake said Mr. Harlow has been working on Martha’s Vineyard since 2009, beginning with Edgartown parking and traffic. He joined the Oak Bluffs force in the summer of 2011 and was asked to stay on. Chief Blake sponsored him last fall for the police academy, where he graduated in the top of his class.

Mr. Harlow’s appointment was confirmed by the Oak Bluffs selectmen on Tuesday, and made official Wednesday in a ceremony at the police station.

“I personally have seen you around town a great deal of time and I’ve always been impressed by your professionalism and demeanor,” selectman Kathy Burton said.
