FAIRFIELD — It was a busy weekend at the beach for police officers, caused in part to a post-St. Patrick’s Day celebration dubbed “Sham Jam” by university students living off campus.

At least four infractions were issued Friday night and Saturday afternoon for open containers of alcohol and possession of alcohol by a minor to beach-area celebrants. The incidents took place near the Reef and Fairfield Beach roads’ intersection, as well as a house in the 600-block of Fairfield Beach Road.

Just after 5 p.m. Friday, police were dispatched to Lantern Point, once the site of the infamous Clam Jam springtime party by Fairfield University students, at the request of Michael O’Rourke, head of the homeowner association, who wanted help in breaking up a large party on the Lantern Point deck.

According to the police report, O’Rourke was concerned about the fete’s noise level and the large number of party attendees. Officers said they could hear “unreasonably” loud music coming from Lantern Point while standing at the Reef and Fairfield Beach intersection.

The Lantern Point deck, the officer said, was “packed with several hundred students,” and the loud music was coming from 743 Fairfield Beach Road, a house the officer had visited a short time earlier to warn resident Nicholas Torna about the loud music and the town’s zero-tolerance policy on such matters. The report stated that Torna agreed at that time not to play music at loud levels.

“As I arrived to the rear of Torna's residence a large speaker, which was standing approximately 6 feet high, and a large amplifier were facing outside from the threshold of the back door,” an officer’s report states. “The music was loud to the point where I could not communicate with students that were in the immediate area of the residence, and I could not hear police radio transmissions.”

Several officers cleared students from the deck and Torna, 22, of East Hanover, N.J., was issued a summons for disorderly conduct. He was released on a promise to appear March 29 in state Superior Court in Bridgeport.

On Saturday, police got a call around 3:30 p.m. from a Fairfield Beach Road resident reporting that young adults were urinating on private property and in front of children. The suspects were gone when police arrive, but the report notes, “Large crowd of students in area due to Sham Jam. Crowds were clearing on arrival.”

Around the same time, a Fairfield Beach Road resident called police to ask for help in breaking up a large party at her residence. Police said uninvited guests left without incident.
