LINDENHURST - Nearly a dozen bikers were arrested Saturday after police say they found guns and drugs at a fundraiser hosted by the Pagan's Motorcycle Club.

Police say that between 7:45 p.m. and 1 a.m., they arrested and charged 11 men with possessing guns and drugs in the vicinity of the gathering.

As News 12 reported, the Pagans were raising money for 13-year-old Thomas Napoli, of Seaford, who has been battling cancer for two years.

They were also celebrating their 50th anniversary and the reopening of their Long Island chapter. The event was held at Duffy's Ale House in Lindenhurst.

The Pagans, who have a history of violence on Long Island, were being closely watched by Suffolk authorities during the event.

In 2002, a clash between the Pagans and their rivals, the Hells Angels, turned deadly in Plainview

The event raised $3,000 for Napoli.

Police say that most of the men who were arrested outside the bar were from North Carolina, Delaware and New Jersey.
