A late-night police raid last week on St. Anthony Hall, a literature and arts fraternity, netted 18 arrests and 27 drug and alcohol charges in connection with the operation of an illegal bar.
N.C. Alcohol Law Enforcement officials raided the house, located at 207 Pittsboro St., after they were tipped off about the bar.
ALE Agent Mike Penland said the agency began a surveillance of the house after receiving an anonymous tip that fraternity members were selling alcohol without a valid permit.
Surveillance lasted approximately two weeks, during which officers observed irregularly high levels of traffic entering and exiting the premise on particular days of the week to purchase and consume alcohol, Penland said.
ALE responded by sending a few undercover agents into the fraternity to attempt to purchase alcohol.
"While inside the house the agents observed an illegal operation of a bar, numerous people in possession of marijuana and underage drinking," Penland said.
"Surveillance and the agents' observations provided sufficient evidence to obtain a warrant."
The raid was carried out by seven ALE agents and two Chapel Hill police officers who were called in for assistance. Authorities found more than 40 liters of alcohol and about 35 grams of marijuana.
Efforts to contact several fraternity members, including the group's president, were unsuccessful Thursday.
