I am seeking advice about whether I have done the right thing in relation to witnessing domestic violence in public. I would also like to know if there is anything further I should do e.g. referring this to the police?
Today I was walking up an escalator beside a staircase in a bus station. At the top of the stairs was a couple. As I got onto the escalator I heard him say loudly that he didn't want to go home. The two of them were standing still at the top of the stairs. As I came level with them on the escalator, I noticed he was twisting her ear and continuing to say they should go home. His behaviour appeared calm, calculated and in control. She was fairly quiet, had a calm tone of voice although I think was protesting slightly, and was giggling slightly although I sensed this was nervous laughter rather than anything playful as I felt his actions were clearly agressive.
Without thinking I said loudly 'Excuse me' upon which they both turned round (he let go of her) and I said firmly 'don't treat her like that'. They were both staring at me open mouthed, and didn't say anything back. My exchange with them was very brief and I then walked away from them, however I have been left wondering if I did the right thing, and wondering will this make things worse for her, should I have spoken directly to her, should I have called the police etc. I felt she was not badly hurt enough to need help in that sense - rather his actions were controlling her and I wanted to make known that people had noticed.
Can you advise what I should have done and if I should do anything further? I felt that I had very limited time to act as I was moving past them on an escalator and my instinct was to stop the action from happening. I didn't feel this gave me time to call the police. I have a very hazy memory of them but know the location where it happened at about 9.08am this morning, he was very large (20 stone at least), scruffy appearance, think he was wearing joggers and a navy blue tracksuit top. She was around 5' 2'', hair in a ponytail, overweight. I would guess their ages to be mid thirties. Other than that I would have very little info to give the police.
