I've always wondered what I'd do in this situation. But I think you were right especially as the odds were even in that there was only two of them. It is dangerous nowadays and a sign of the times that you have to consider your own wellbeing before 'jumping in'.
I would also not give a statement as Big Mick has said, from my own experience with the old bill.
I once lost a credit card and a lad tried to use it but failed as the shop assistant saw my name on it and as I'm a girl she realised there was something wrong...

The shop prosecuted the lad and I was asked to give a statement which I did. But I made it clear that I didn't want to press charges. As far as I was concerned he was a school lad who'd made a mistake, no purchase had been made on my card, so no harm done.
The police said they wanted a statement to prove I hadn't given him my card

Anyways Daws hope all goes well with it for you.
