Ive encountered him twice on Matham Grove. The first time, just over a week ago, i had the hostel story and gave him a couple of quid. The 2nd time was Monday evening. When he started the story again I told him i wasnt falling for it twice and kept walking briskly. He started shouting and swearing and I didnt hang around. He does seem a bit unhinged and I would be cautious if you see him.
