Police turned up at the door the other day and were unfortunately let in by my very distressed mother before I got to the door (I would have checked warrant, ID etc through door first). My brother and I went to help our mum and after we ascertained there was no warrant, or clear reason for entry, asked them to leave. They refused and we asked several more times, but still refused. With hindsight I should have called their superior but was wondering was that legal for them to remain in the property despite 2 occupants who would not have let them in asking them to leave? My mother is elderly and could not make that decision, in shock, herself rationally.
