I was also at the train station yesterday and I could hear a woman screaming. She was being held by a man, who I assume was her partner and he wouldn't let her go. In a brilliant show of human solidarity the two hundred or so people who could also hear it, put their heads down and looked the other way. I eventually found a community police officer by which time they had moved on. It is always horrible to witness violence, and particularly when it is clearly within a domestic relationship. I don't think I could have helped by intervening myself - it would probably have made the situation worse and at the same time I wish I could have found security or the police sooner. I hope she is ok.
