Vermont State Police cited 30 people traveling on buses with the Boston University Ski and Board Club with possession of alcohol or drugs at a Canadian border crossing Monday.
It was unclear yesterday how many of the passengers were Boston University students.
Colin Riley, the university’s executive director of media relations, said the university is investigating a group of its students who were issued citations and is handling the incident the same way it handles similar situations in Boston.
“If they were cited in Boston, the Boston police send those over to us, and we call the students in and ask them to explain the circumstances,’’ he said. “We’re handling it just as we would any violation.’’
Around 2:10 Monday afternoon, Vermont State Police responded to the US-Canadian border at Interstate 91 in Derby Line, Vt., where they found a line of eight buses, according to authorities.
US Customs officers found that several passengers, who were returning to Boston after skiing in Quebec, were under 21 years old and had alcohol with them, police said in a statement. The legal drinking age in Canada is 18 years old.
Vermont State Police issued 26 citations for minors in possession of alcohol. Additionally, they cited four passengers to appear in Orleans District Court to face drug possession charges.
Kelly Greacen, 19; Aanchal Khaneja, 22; and Dylan Turk, 19, were cited for possession of marijuana. Laura Eldred, 22, was cited for possession of ecstasy.
On its website, the ski club refered to the weekend trip to Quebec City as its most popular and promised, “it will be the time of your life!’’
On the homepage, the group declared, “We have no classes on Monday and are taking advantage of the long weekend to get down in good ol Canada!’’
The website also notes that the group is partially funded by the university’s undergraduate student fee and advises that “friends at other schools are welcome to come on some of our trips that are not directly funded by BU.’’
It was unclear yesterday if the weekend trip to Quebec City was directly funded by the university.
Officers listed on the group’s website did not immediately return an e-mail seeking comment.
