I also suffered a theft in Dulwich Library around this time last year. I had my daughter with me in the pushchair, and had gone around to the bathroom, where the disabled toilet/buggy accessible one, was out of action so I had to take her into the bathroom with me, leaving her buggy outside. I stupidly left my mobile phone tucked into the hood of the pushchair. I went around my business in the library and realised my phone was gone. Thought back to last having had it, and realised that it must have been taken then from outside the toilet. The library staff were kind at the time and helped me to phone the police (obviously I had no phone to do it myself) but the library has no CCTV in the bathroom lobby area so there was never any use in the police looking over the library CCTV anyway. I was annoying, and upsetting, but ultimately it was my own fault really for leaving it there. It still does make you feel vulnerable as a library feels a safe place more than the usual shop maybe would.
