BOSTON, Sept. 22--Four Negro teen-agers were shot and wounded early today in what police described as a riot which erupted at a rock 'n' roll record hop in Boston Arena and continued on adjoining streets. They said the riot followed a fight in the center of the big dance floor where a Negro youth was dancing with a blonde white girl, but they did not label the incident "racial."
Police made no arrests immediately, and none of the three boys and one girl who suffered bullet wounds was considered in serious condition. Witnesses said the first fight led to about five others among the crowd of 1400, described by police as predominantly Negro.
At the height of the excitement bands of teenagers burst from the Arena, fought among themselves, accosted motorists and even pulled some drivers from their cars and roughed them up on the street.
