Whilst I was waiting to cross the road recently, I was assaulted by someone who threw water at me from a passing van, hitting me right in the face. As you can imagine I was stunned but managed to see that the person who did this was a passenger in van belonging to a well-known engineering company, I didn't see the reg - but saw the livery. I reported the incident to the company who said they would be able to find out which one of their vehicles was travelling down the road at that time as they are all installed with a tracker system. I also reported the incident to the police who decided (eventually) to investigate and I was advised not to contact the company again. Long story short, police have said there is nothing they can do as no CCTV footage and company are saying they can't identify which one of their vans was in the area as not all are fitted with a tracking system - this is not what the company told me when i initially spoke to them. The police have said that I can take the matter up again with company but I'm not sure how to take it forward. Any ideas?
