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

South Beach, liquor stores and liquor serving establishments were the target of a special underage enforcement operation.

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

Al’s Package Store, Sophia’s Market, the Wharf Pub, Sharky’s, the Newes From America, and Henry’s bar at the Harborview Hotel failed the compliance checks. This will be the second citation for the hotel in the past month.

“Our goal is to work closely with these establishments and achieve a much better success rate the next time around,” Det. Sgt. Chris 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.

In an interview with the Gazette, Mr. Dolby said the police department took a week to plan the operation that involved between eight and ten police officers.

“In order for us to get that many bodies together and do something like that it’s a big deal, we don’t have a lot of resources this time of year,” he said. “We have to do a lot of planning to cover this and the normal business.”

“We’re not pleased with the outcome,” he added. “We’re hoping this information passes along to the underage kids so they don’t conduct that type of behavior out there.”

Mr. Dolby said the police recognize underage drinking is “going to be out there, but we’d like to have it be nonexistent.

“We’re not kidding ourselves, but we want them to know in the back of their minds that an officer could be sitting in a bathing suit behind them and they could go to jail,” the detective said.
