A man has been arrested after police revealed that a driver who fled a hit-and-run crash which killed two pedestrians may have buried a suitcase stuffed with cash nearby.

Two men, thought to be in their late teens to early twenties, were killed when a BMW hit them on the B1091 in Yaxley, Cambridgeshire.

It is being investigated whether the suspect – who left on foot – is responsible for a break-in at a nearby address and a dumped briefcase full of cash, police said.

Reports suggested it may have amounted to £100,000.
