DALLAS -- About 50 fans of the rap group 2 Live Crew rampaged Saturday night when a concert was canceled, smashing tables and chairs and hurling bottles at the stage, witnesses said.

Several people suffered minor injuries, but no arrests were reported.

Police declined to provide any details on the disturbance.

At 11:15 p.m., more than three hours after the concert was to begin at the Longhorn Ballroom, an unidentified person announced over the public-address system that the band would not appear if it did not get paid, witnesses said.

Twenty minutes later, the band's stagehands began packing up their equipment.

A man jumped up on the stage and demanded his money back, and the crowd of 540 turned surly when security guards dragged the man away, witnesses said. About 50 people turned violent, smashing the wooden chairs and tables, while most of the crowd spilled out of the building, witnesses said.

Security guards soon forced the protesters outside. Several windows were broken and some cars in the parking lot were vandalized before some 50 police officers in riot gear arrived and dispersed the crowd, witnesses said.

The ruckus lasted about 12 minutes. A damage estimate was not immediately available.

The band, whose album "As Nasty as They Wanna Be" has been ruled obscene by a Florida judge, never came onstage.
