An undercover sting on the Island's East End led to the arrest of 15 people over Memorial Day weekend.

Southampton police said they found thousands of dollars of drugs at Neptune's Beach Club in East Quogue. Marijuana, smoking paraphernalia, steroids, the date-rape drug GHB, percocet, ecstasy and cocaine were all confiscated, according to police.

A dozen people were arrested in the Tiana Beach parking lot, while three others were taken into custody at Neptune's.

The New York State Liquor Authority had already been investigating Neptune's regarding a disorderly conduct charge. Neptune's faces the loss of its liquor license or a fine. Police and residents each said they hope the club loses its license.
