Traumatising last couple of days: Offloading

Long story short: Wednesday both my daughters went to the shopping centre where her school is. All was good. They had breakfast around 11am and dinner was ready when they got home. They arrived home and everyone, including myself, had bit of a row. Both my daughters left the house but then 2 minutes later one of my daughters come home sobbing and my eldest has now run off. 

She switched her phone off around 8:15pm, I told her to be home around 8:30pm. I tried calling people who she may of been with but they didn't answer. She had gone back to where her school was, 40 minute bus journey. She then walked to Town, which is a 2 hour walk but would take her longer, and it's all next to dual carriageways. She then slept on a bus stop bench on the highstreet with homeless people. She said she was talking to them and everything. She said around 5am this morning, this man who was drunk and high tried taking her to his flat to have a drink, eat and watch TV. She walked with him but stood her ground saying that she will wait outside the building whilst he makes her a drink. When he went in she ran back to the Town shopping centre. 

10 minutes later she is kicking security who came over to see if she was ok (she was lying on the floor trying to sleep). Around 8am she was detained then 8:45am, if it was even that time, she was arrested. She was arrested for: common assault on an emergency worker x2, common assault x2, assault casuing ABH (actual bodily harm) and criminal damage to property under £5000. 

She said that security and police were absolutely horrible, trying to break her wrist and using too much force when she was just standing still. She was put in a cell and she destroyed that, graffiti using chalk on walls, chucking drinks and food on the floor, ripping everything up. She then had blankets over her face which she refused to take off so they had to do it. She then tied something around her neck leading to some medical issues, and self harming using the paint off the wall. She was moved to a different cell where she calmed down. We got home last night just after 10pm and this morning she is really poorly.
