Very sorry to hear this, guarantee no insurance, so probably a waste of time trying to find him.
I had the same when a guy ran into the back of me and just drove off, unfortunately he left his front
number plate behind, so old bill had no prob tracing him, but he had no insurance, so he got £100 fine
for no insurance and I got a repair bill of £1,250 on my Merc. Not fair.. :rant:
