Sleepy Hollow police busted another underage drinking party in Westchester over the weekend.

According to police, more than 100 people were crammed into an apartment in a Depeyster Street building for a 20th birthday party Saturday night. Detectives say the hostess advertised her celebration on MySpace.com to just 15 people but word spread quickly. Sleepy Hollow police, along with members of Greenburgh?s Drug and Alcohol Task Force, went to the apartment and found beer and liquor.

The girl who threw the party was charged with first-degree unlawfully dealing with a child. Six other underage partygoers were also arrested and charged with possession of alcohol with the intent to consume.
