Assault on a train

Like most people, I don't like going on public transport. This was made worse for me back in January 2012 when I was assaulted on a train after a day out with my friends.
There was five of us going to Nottingham for an afternoon of shopping and cocktails, to celebrate Gary and I getting engaged.
We'd all had a lovely day and caught the last train home, which was about 8.45pm. The train wasn't busy so we managed to get 2 tables of four, 3 on one table and 2 on the other. We'd not long set off on the journey, when a lad (in his lates 20's) plonked himself next to one of my friends', right on top of her shopping bags and said "my name's Daniel and I'm hilarious". I begged to differ!
One of the other girls told him we were having a girls' day out so could he go and sit elsewhere as we hadn't invited him to join us. He started getting a bit rowdy, so we called the train guard over. That's when the verbal abuse started, first at the poor train guard and then at us. I was just trying to ignore him, hoping he'd get bored and leave. But this seemed to wind him up even more, and out of nowhere he punched me on the side of my head! I yelled out with shock and pain and he was right up in my face saying "yeah, what you going to do about it"
One of my friends was already on the phone to the police, who had the train stopped at the next station, while we waited for them to arrive.
Meanwhile, I'm stuck on the train with the man that just assaulted me, as he paced up and down the aisle shouting obscenities right next to me.
I know I was in shock, I really couldn't believe what had happened. I faced the window and text Gary to let him know what had happened.
The police arrived along with a police dog, but Daniel did not go quietly. One of the transport police came on to the train to ask if I wanted to press charges. I asked what that would entail and he said I would have to go to the police station with them now and make a statement. That immediately made me say no, I just wanted to go home. He had a word with another officer and said I could go home and they'd ring me later to get a statement. Thank goodness.
Gary had been out with his mates too, but raced home to meet me and give me a much needed cuddle. The police rang shortly after I'd got home and I gave my version of events over the phone. They offered to send someone out to photograph my injuries and gave me a number for Victim Support.
The next evening the same police officer came to the house to take a victim statement off me and get all mt friends' details so they could give witness statements.
Luckily our statements were so detailed and the CCTV on the train was so good, that none of us had to appear in court. He was found guilty of assault, which was great, but it certainly had a lasting effect on me....
