Police on July 4 responded to a call at a home in the 700 block of Rollingwood Road in Stone Mountain-Gwinnett County for possible underage drinking.
A complainant told police he picked up his younger sister from the address and saw young people drinking.
In one of two reports about the incident, which started around 11:30 p.m. July 4 and went into July 5, police say they saw a male who "appeared to be young" get a beer from a refrigerator in the garage. Officers asked him who owned the home; he responded that it was his friend's parents' home and went to get them.
Police said as they neared the door to the inside, they could "see multiple people inside playing beer pong and drinking beer from cans."
Police said a girl yelled that the police were there and a male pointed to the beer pong table and told everyone to hide the beer. According to the report, no one knew the police were standing there and could hear what was being said.
At one point an officer said he asked who was under 21 and several people raised their hands. One person who said he was under 21 "stunk of an alcoholic beverage and his eyes were bloodshot and glazed," according to the report.
The first male police met returned with the homeowner, who told police that his son could come back home from a party and hang out with a few friends, police said.
According to the report, the homeowner said he knew they were drinking and would rather them do it at his house than somewhere else.
One officer arrested the man for furnishing alcohol to minors; the homeowner was taken to the Gwinnett County Detention Center.
The other officer on scene arrested two other men, who, according to the report, told police they knew there were people under the drinking age at the home and that they weren't allowed to provide alcohol to people that age.
According to the report, after one of those men was arrested, he yelled to the under-21-year-olds, "Thanks a lot."
