My immediate neighbours ex partner has come to her house on two occasions within 1 week banging on all the doors and windows aggressively for over 20 minutes at a time. He trespassed into her back garden to get to the back door by climbing over the fence as the gate is visibly locked from what I can see. Should I call non emergency police if it happens again or go straight to 999? I don’t work and spend a lot of time in my front garden so know my neighbour is home when this is going on and there is also a small child in the property. I can only imagine how scared they are. I feel awful for not opening the door and telling him to sod off but don’t want to risk him being violent towards me. From when I’ve spoken to her I know he’s moved out so he’s not locked out or anything as it’s not his house
