Fraudulent injury claim after bump

[Killer2005]

Chaps

My mother was involved in a crash in her works car park in November 2012, in which a bloke entered the car park entrance too quickly and hit the front offside corner of my mums car and scrape down the offside door, however not sure of the damage to his car but from what my mum said was not great. At the time, the insurers somehow came to the conclusion that was 50/50 and processed it as that.

This week my mother has received a summons from court stating that the bloke is now claiming it was a head on crash, his car was written off and he's now mysteriously suffering from whiplash etc

I believe my mum may have the pictures of her car after the incident, and I've told them to go straight to the insurers with this, but is there anything else that could be done?

Thanks
