I got nicked early morning. They wouldn't let me make a phone call but they would make it for me. Then they wouldn't let me have my mobile to find the number I needed, which was someone to pick up my kids (aged 13 and 15) and take them to school. I also wasn't allowed to contact them later in the day to tell them where I was. Bearing in mind they'd witnessed their mum being arrested and carted off in a police van and more than a dozen coppers ripping their home apart.
The cell was absolutely freezing, they took my coat cos it had a cord on the hood. The blanket was as stiff as a board and had blood stains on it, amongst others. The toilet was blocked up and right by the bed. I had to go to another loo with a policeman standing in the doorway. They wouldn't answer the bell and they didn't give me any food all day.
I was released on to the street at 10pm with no phone and no money. My kids, having walked home from school and fed themselves, still didn't know where I was.
Not as horrendous as most stories but fairly unpleasant and not what the rules state
