MEDFORD, Mass. (AP) — A top administrator at Tufts University is reprimanding students for alcohol-fueled misconduct during an annual event at one of Boston’s top hotels.

Dean of Student Affairs Bruce Reitman said 15 to 20 students who attended the annual Winter Bash at the Westin Copley Place on Feb. 1 required medical attention for excessive alcohol consumption, while some students urinated or vomited in the hotel’s bathrooms and lobby.
