A friend of mine studies at an American university in the UAE. Recently, he was literally escorted out of the campus building on the premise that it was winter break.
It is a common notion that the university remains closed during the winter break, but he is a full-time student and was on the campus for more than 24 hours. The university is heavily guarded and is always monitored by a Public Safety department which is actually run by a multinational security corporation (originally based in the US). The presence of my friend was already known and he has been a student for more than 3 years. He was working on a project, and is a kind of person who gets lost very easily in work. First night, he crashed in during the night because he lives in a far away city (in his case, Dubai) and continued working on his project the next day as well. The university is a very student-focused Liberal Arts university, and he was in no way ready for what was to happen.
While he was working in one of the labs which is usually 24x7 for student use, two security guards approached him and asked him to leave the campus immediately. The demeanor of the guards was very rough and they kicked out this student and asked him actually to leave the campus (entirely) at around midnight. Now, my friend is literally left devastated by this act which they carried out on him at midnight. He now hates his university and is scared of the Public Safety officers (who are supposed to protect him). He immediately wrote to them asking what the actual protocol was for some student who would come to campus during a break, but hasn't received a response since (almost ten days now).
Can he sue the company managing the Public Safety department (for the psychological damage he received)? He has witnesses, including me. On what grounds can he file a case?
EDIT: The university is a residential education-based university that means students live there 24x7 except during the break, and during that time only the housing is shut but all the other major facilities are accessible. So all the places my friend accessed were done so using his university issued RFID-based ID card. So far, the Public Safety department has not given any official reply to his question about what the actual protocol is. It seems that there was no such protocol to deal with such a case in the first place but the security officers on duty that night just did it on a whim.
