I was walking down East Dulwich Grove (towards Lordship Lane) on Tuesday 6th at 13:35 when a man came out of Thornecombe Rd and headed towards me. I had a sense that he was going to approach me, but put it down to paranoia. As he became parallel to me he almost turned around and grabbed me in between my legs. It lasted a matter of seconds and he then ran off into the housing estate, not before stopping and having a look back at me. As you can imagine I was pretty stunned, but felt it was serious enough to call the police who were there in a matter of minutes. We drove around the area but with no luck. He was a tall white man, about 6'2", spiky mousy hair, he was wearing all beige-beige sweat shirt and cambat-like trousers, he also had sunglasses on. This was a very bold attack on a busy rd and I am concerned that not only will he do it again, next time it could be in a less busy area and therefore more servere, please keep your wits about you!! The police think that he was probably a local man as he would have had to know the estate.
