One of the UK's biggest car insurers says the number of crash for cash claims from fraudsters went up by more than 50% last year.

Aviva wants harsher sentences after it had more than 6,000 motor injury claims linked to organised fraud activity.

The insurer put the value of claims from what it called induced accidents at more than £10m.

They've released footage of one such crash, where an innocent driver - who has a dashboard camera - ends up crashing into fraudsters.
