I was in the Brixton area last night and while driving down Brixton Hill I spotted a street girl eyeing up cars as they passed. She was walking towards Streatham Hill. I haven't seen anyone working the street for quite a while so out of curiosity I decided to get a better look. Knowing there is CCTV everywhere I parked up a little further away on a side street and went on foot. I was planning to have a look only and not punt, but took some cash, just in case! I left my wallet in the car as street girls are notorious for picking your pocket. I went walking up Brixton Hill towards Streatham and spotted her walking back towards me. As she got closer I saw she was a black girl in her mid 30's dressed in black leggings and a black puffer jacket. She looked like a heavy user to me so immediately I decided nothing was going to happen. She looked at me as we passed but neither of us said anything. I continued walking towards Streatham and as I looked back I saw her watch me and nodded towards me. I continued walking. She then crossed the road and approached a parked up car by the Tesco Express near Brixton Prison. She spoke to the driver but then walked away. There didn't seem to be any other girls working in the area. I had seen enough and I did a U-turn and want back to my car.
