Car accident - overtaking at a junction?

I was involved in a car accident this September and I am not claiming liability as the third party overtook 3 stationary vehicles in a line of traffic at a junction I was pulling out of. The 3rd party "dragged" their car across the bumper of mine and drove off. The 3rd party was not indicating and drove onto oncoming traffic. 3rd party did not stop and I had to drive up behind them and flash my lights to get them to pull over. Police arrived and 3rd party did not admit liability and police did nothing. Checked out Highway code and states that it is wrong to overtake at junction. This is still ongoing and very upsetting that 3rd party lying and saying I "pulled" into them! Any ideas?
