PLAINVIEW, N.Y. - Rival motorcycle gangs armed with daggers, baseball bats and a machine gun clashed at an indoor motorcycle and tattoo expo called the Hellraiser Ball, authorities said. One man was killed and at least 10 people were injured. <br>
<br>
About 60 people were in custody Saturday night and the number could grow, said Nassau County Chief of Detectives Herbert Faust. <br>
<br>
Faust said four people were shot, one fatally, and others injured when the fight erupted around 4:15 p.m. at the Vanderbilt, a concert and catering hall in Plainview, N.Y. <br>
<br>
Faust said the fight broke out between members of the Hells Angels motorcycle club, whose Long Island chapter sponsored the event, and a rival gang, the Pagans. <br>
<br>
As many as 100 Pagans showed up at the event, which drew about 1,000 people, many of them Hells Angels members, Faust said. <br>
<br>
``There's been a long-standing feud between the two motorcycle gangs,'' he said. ``At some point, there was a major conflict. We have gunshots, we have people stabbed, a major fight.'' <br>
<br>
Several people who fled the scene were apprehended nearby, Nassau County Police Commissioner William Willett said. <br>
<br>
Police also recovered numerous daggers, baseball bats and an Uzi automatic weapon, Faust said. <br>
<br>
The expo had been under surveillance by police, but was not expected to be violent, he said. <br>
<br>
``We had surveillance. We were aware of the event. We had no reason to believe it would have erupted into this type of conflict,'' he said. <br>
<br>
One man died in surgery and two others were being treated at North Shore University Hospital in Plainview, according to Betty Olt, a hospital spokeswoman. She would not describe their injuries. <br>
<br>
Nassau University Medical Center had treated nine injured people, hospital spokeswoman Shelley Lotenberg said. <br>
<br>
Police were searching for more suspects. <br>
<br>
Scott Casagrande of Medford, N.Y., said he was displaying a motorcycle at the show when he saw ``a herd of people running toward us, saying 'Get out, get out, there's gunshots.''' <br>
<br>
``Everybody ran,'' he added. ``I heard gunfire downstairs but I thought nothing of it because a band was playing. It was very loud.'' <br>
<br>
According to the event's Web site, tattoo and piercing artists, motorcycle shops and other vendors paid up to $300 to rent space at the expo.
