A resident of the area called police and reported seeing minors enter the home with alcohol, according to Wellesley Police records clerk Sue Morse.

Police responded to the area and could see multiple young people looking out the front windows at the police, when they approached the house, they could see teenagers in the kitchen area drinking, Morse said.
