Dozens arrested at latest concert Sunday, August 19, 2007 At least 53 people were arrested for underage drinking last night at the Beat Stock concert at the PNC Arts Center. The arrests came one day after alcohol consumption was banned in all Arts Center parking lots. State Police beefed up patrols at the Holmdel venue this weekend to try to rein in the drinking. As fans began arriving yesterday afternoon, they found uniformed and plainclothes officers patrolling the lots as well as the rest stops along the Garden State Parkway and New Jersey Turnpike to enforce the ban, said Sgt. Stephen Jones, a State Police spokesman. The 53 arrests, all for underage drinking, were as of 9:15 p.m. The alcohol ban was prompted by a summer season during which alcohol and drug problems have been rampant at PNC. It was announced Friday after two people died from alcohol and drug poisoning and more than 80 people were arrested during the "Ozzfest" concert Thursday. Joe Orlando, a spokesman for the New Jersey Turnpike Authority, which owns the property, said officers issued several warnings during Friday night's Velvet Revolver and Alice in Chains concert but made no arrests. He expected the police to be busier last night because the annual Beat Stock show attracts a younger audience. Despite the 53 arrests, Orlando said, most concertgoers caught with alcohol in the parking lots were cooperative when asked to pour it out. Jones said State Police investigators were combing Internet sites in advance of yesterday's concert and found several postings where concertgoers were discussing places to meet -- off property -- to drink before the concert, which began at 6 p.m. .
