I was just told by an acquaintance that an incoming intern at my company was apparently suspended for college for sexual harassment, and has been on leave for the last semester and the current semester. The acquaintance provided pictorial evidence to show that the allegations of suspension are in fact true. I believe that this intern lied to HR and told them that he was taking time off to travel, and I do not believe that the HR is aware of the suspension, as we generally do not ask for transcripts or other information from the school itself. What should I do in this situation?
