Out of 21 establishments that underwent a Brunswick Police Department’s underage drinking sting conducted Aug. 3 — police say all but one passed.

The police department has conducted underage drinking stings for establishments that hold permits and licenses for alcohol on- and off-premises since around 2008, according to police officer Terry Goan, following the dissipation of the state bureau of liquor enforcement, in an effort to continue enforcement efforts within town and ultimately prevent underage drinking.

On Friday, Aug. 3, police ran a sting operation that focused on establishments with off-premise licenses, meaning the alcohol sold can’t be consumed on the premise. Goan said police worked with a 20-year-old female, who entered the establishments and usually selected a fruity drink such as Twisted Tea, and brought it to the register where the clerks are supposed to check for ID.

After visiting 21 establishments over the course of about five hours, Goan said the Circle K store on Bath Road was the only establishment that didn’t pass and failed to check for ID. It was issued a ticket for selling alcohol to a minor. The report and ticket goes to the Maine Department of Public Safety’s bureau of liquor licensing, which hands down a sanction at its discretion, taking into account many factors such as other company stores in the state that have had violations.

Goan said normally the stings utilize the help of minors between the ages of 18 and 20 who volunteer for the job of trying to buy alcohol. The police will next focus on establishments holding onpremise licenses where customers are not to take alcohol off the premise. Goan said the department aims to conduct the underage drinking stings a couple times a year.
