Really sorry to hear this has happened to you. Thank you for sharing and giving others a heads up. Sounds like you had a narrow escape, no doubt you will be suffering shock at the moment. It's difficult to defend against situations like this in London at least you have survived unharmed.
It's something that can always happen. Certainly reminded me that it's still happening and to take care. Beyond that it's just bad luck that your paths crossed.
