I know the guy, he lives in the Tower Blocks on Frien Road. I would be surprised if it was him who did that in the park as he has only been verbally abusive (very) to women from what I have seen on several occasions (and yes I did intervene). Doesn't seem to pose much of a physical threat but I would be wary of him if I was a women because basically that would mean he hates you. He is mentally unwell and obviously isn't getting any support. The reason he has a pole is that he is trying to start up a window cleaning gig, which is also why he knocks on doors.
