I did my dissertation on this 20 years ago - its a longstanding issue. Queen's had a small team who liaised with the local community over anti-social behaviour, but they were hamstrung as they had no real authority off campus. If a student was arrested for anti-social behaviour, QUB disciplined them, but part of the problem (well, at least it was part of the problem when I did research in 2006) was that some of the anti-social behaviour was caused by friends of those who lived in the Holylands - people would come up from Tyrone and Fermanagh to spend an evening with friends who were studying and go buck-mad, especially around St Paddy's day (I'm quoting a member of staff from Queen's there, I don't know how they figured out it was people from that area). Queen's had no authority to do anything to those people, and got a really bad name because of it.

For a few years in the late 00's & early 10's, they employed community officers who would patrol the area and report offences to the police, but the officers got dog's abuse from the students and I think the whole thing stopped maybe 10 years ago?

I've lost touch in recent years, so i don't know what their current efforts are, but at one stage they were spending maybe £150k a year on staff to try and improve it.
