Sigma Chi fraternity members at Rutgers University allegedly drugged members of a sorority during a mixer this past fall with punch spiked with Xanax, according to records obtained by the Daily Targum.

The New Brunswick chapter of the Sigma Chi frat was shut down in November, but the university didn't disclose the reason for its closure, the Rutgers student newspaper reported.

Rutgers University spokesman John Cramer said the school reached a mutual agreement with the national Sigma Chi fraternity to suspend the New Brunswick chapter following an "investigation into reports of policy violations."

"All operations and activities of the chapter are terminated until August 2020, after which the national organization may consider establishing a chapter with new members, without the involvement of suspended members," Cramer said. "In addition, the Sigma Chi national organization agreed to directly inform all members still on campus that, for the remainder of their undergraduate careers at Rutgers, they must cease any and all fraternity activity."

The school later amended the statement, saying that the suspension was not related to the allegedly spiked punch.

A source told The Daily Targum Xanax was put into a communal container of alcohol and fruit juice during the mixer with the Sigma Delta Tau sorority on Sept. 16. Frat members were the only ones who allegedly had access to the communal container.

Records obtained by the student newspaper reported about 10 sorority members suffered bouts of vomiting, incoherence and black outs. The spiked punch also reportedly interfered with one individual's prescribed medication.

Cramer said student privacy laws bar the university from providing further comment on any additional aspects of the student conduct investigation.

Two months before the frat chapter was shuttered, the school issued a cease-and-desist order barring it from holding parties.

Messages placed on Friday to the national Sigma Chi organization and the local Sigma Delta Tau sorority haven't yet been returned.
