It might be different here in Northern Ireland but myself and a lady were caught pretty much the same way as your self. Just after we had finished and gotten dressed they appeared and quizzed us. Police here are aloud to ask you your name, date of birth, we’re you live and what you were doing.
They were pretty chilled out once they realised we wernt dealing drugs or stashing guns in the forest lol they explained that the area was knowen for just the likes of drug dealing and weapon stashing. Let us go and told us to be careful
Thinking back now they 100% knew what we were up to lol
