Six Edgartown establishments have been reported to the selectmen after an under-age alcohol sweep by the town police on Friday.

The Edgartown police department’s underage alcohol enforcement operation targeted three areas: South Beach, liquor stores, and liquor serving establishments.

Arrests were made at South Beach and summonses were made at liquor stores.

Al’s Package Store, Sophia’s Market, the Wharf Pub, Sharky’s, Henry’s bar at the Harbor View Hotel and the Newes from America pub failed the compliance checks. Police forwarded violation reports to the Edgartown board of selectmen. “Our goal is to work closely with these establishments and achieve a much better success rate the next time around,” Det. Sgt. Christ Dolby said in a statement about the operation.

After police received complaints of underage drinking at South Beach, adding to concerns voiced by members of the Martha’s Vineyard Youth Task Force, on the afternoon of July 15, uniformed and plainclothes officers were assigned to the beach. Following their observations, police made four arrests and five summonses for the offense of minors in possession of alcohol.

At liquor stores in town, uniformed and plainclothes officers issued two summonses (alcohol; minor transporting and minor procuring using false identification) and two $500 citations for consuming from an open alcoholic beverage while in a vehicle.

The compliance checks at establishments serving liquor involved an underage subject attempting to purchase alcohol or gain entry into the bars and then attempt to purchase alcohol. When asked for an ID, this subject produced his driver’s license which indicated that he is 19 years old.

Detective Sergeant Dolby said in the statement that “the objectives of the operation were to enforce underage alcohol laws, deter underage alcohol consumption, and educate people in regards to the alcohol laws (under 21 people and employees who serve/sell alcoholic beverages).”
