Sarah was still crying. She went to help Andy and the short-haired lad who was near him just punched her.
That was it, I'd had enough and I started to yell for the police as loud as I could. I remember thinking there must be somebody around with a mobile phone to call 999!
Funny thing, the thugs seemed to stop then and go away except I saw that short-haired one gave Andy a last kick.
Andy was looking really bad. I bent down to see if he was all right. There was a pulse, thank goodness.
