An MIT student visiting Wellesley College was hospitalized after he fell about 12 feet inside the Lulu Chow Wang Campus Center around midnight Saturday, police said. The student fell inside the building, from the third floor to a landing on the second floor that juts into the building’s open atrium, Wellesley College police Sergeant William Bowman said. The injured student was taken to Beth Israel Deaconess Medical Center in Boston, Bowman said. “He was conscious and was able to speak to the officer,” Bowman said. A Wellesley College police officer is investigating. Bowman said he did not know whether drugs or alcohol were involved. The center is open to students 24 hours a day. There was a concert on a lower floor earlier Saturday evening.
