i agree amy... i would feel the same as the op... i'm just stating the police have to act to stop a possible scene occurring - if they felt allowing him to stay could cause some other problems...(perhaps the woman expressed a fear for her safety etc?)... then they had to control the situation ... and from their point of view, she said she lived there, the neighbours agreed with her, all her stuff was there and she had a key - he on the other hand couldn't prove anything at all - no letters, bills, documents, no belongings, no nothing to show he lived there...even the neighbours said they didn't think he had any rights either - who would you believe - at the time ....?
i'm not saying they were right, just that lots of people are inconvenienced by the police... we don't all get compensated for it... as i say its worth a try though...i would certainly try...
