Bloomington businesses passed the city’s alcohol compliance checks with flying colors in 2015, as the city’s police found that not one of 128 businesses tested had tried to serve or sell alcohol to minors.

“We rely on the businesses who sell alcohol to keep it out of the hands of minors through extra efforts and employee training,” Bloomington Police Chief Jeff Potts said. “Our hope is always for zero violations, so this extraordinary level of compliance is a big deal.”

In 2014, four Bloomington businesses were found to be in violation out of 125 checked.

The checks were conducted under police supervision by minors from 18 to 20 years old, who were sent into bars and liquor stores to try to buy alcohol with ID showing they were underage. The checks are made once a year to ensure that businesses are following state law.
