Boise police gave out 99 tickets while breaking up a massive party near the Boise State campus late Saturday, including 89 citations for underage drinking.

The other 10 tickets were for disorderly conduct and having an open container of alcohol, according to Boise Police reports.

Police were sent to the party, at a home in the 1500 block of Grant Avenue, shortly before midnight Saturday after getting complaints from neighbors about loud noise and possible underage drinking.

When officers arrived, they found about 250 people at the home and the area around it. Police say many of those people tried to run away. Others tried to hide inside the house in the attic or backyard, police say.

Boise police had extra patrol officers on duty Saturday night who were being paid overtime from a State of Idaho grant to curb underage drinking, Boise Police Officer Jermaine Galloway said. That allowed officers to set up near the house and corral many of the partygoers before they were able to leave, he said.

Galloway estimated that almost all partygoers were under the age of 21. As of Monday morning, no one had been charged with providing alcohol to minors. Galloway said it appears many of the partygoers brought alcohol with them to the party: officers saw several people walking up to the party carrying alcohol.

Boise police had been getting complaints from residents of that neighborhood, which is south of campus between Boise and Broadway Avenues, for more than a month about underage drinking and loud parties in the area, Galloway said.

Saturday’s party was one of the biggest Boise police have busted up in years, Galloway said.
