I saw a young lady bent over railings along Walworth Road. All of a sudden she started up and began flailing her arms around manically. There were some other people that saw her and they obviously thought she was fitting, so for some reason they tried to get her to lie on the ground - instead she struggled away from them and began runnning South, towards E&C, arms and legs and head all moving violently. I think she may have been possessed, or at least she may have thought she had been. Might have been drugs I suppose. Last I saw of her she was stumbling in the very middle of the road. It was very busy, 6pm. Don't know what happened to her.
