About half of those charged in connection with a series of pre-St. Patrick's Day parties at the University of Massachusetts in Amherst last weekend were not students at the school.
The Republican newspaper of Springfield cross-referenced the list of those either arrested or issued a court summons against the student directory, and less than half attend UMass. One UMass employee was also charged.
A UMass spokesman says the campus has received a breakdown of student to non-student arrests. Campus officials have previously said students arrested are subject to school discipline, including possible expulsion.
The drunken, rowdy parties drew thousands of revelers and received national attention. Four police officers received minor injuries from bottles and snowballs thrown by partiers.
UMass' chancellor says the attention "brought shame" to the school.
