Harvard police are investigating a possible hate crime after the university filed a complaint over vandalized books on Friday. All of the approximately 40 books that were vandalized, allegedly with urine, addressed topics related to Lesbian Gay Bisexual and Transgendered issues, student paper, the Crimson reported on Sunday. When library staff discovered the vandalism an empty bottle that appeared to have contained urine was also found. “The [Harvard University Police Department] has zero tolerance for any bias-related incidents or crimes,” a police spokesman told the Crimson. The Harvard College Queer Students and Allies group called the case “disconcerting.”
