Initially reasonable approach, officers based out of here closed the blinds to protect GDPR, Firefighter gave me a stern look but didn't bother me, then PC Elson approaches me a little too closely, but I can forgive him as he didn't cause me too much grief, then the Sergeant approached me, was initially fairly alright, said he was closing the gates, so I had no issue with leaving the car park at that point, then he said if I was to re enter, he would arrest me for aggravated trespass, which is wrong, as It would not have been aggravated trespass.
