Police have confirmed that the car involved in a crash that killed two foals left the scene.

Metropolitan Police are appealing for witnesses after a crash at around 8.50am on Saturday (October 7) between junctions 24 and 25 in Enfield which caused long Hertfordshire delays.

A car, the force believe was a dark-coloured VW Touran, collided with a horse box carrying two five-month-old foals which was being towed by a van.

One of the horses was killed in the collision while the other had to be put down due to its injuries and police have now revealed that the car driver left the scene.

The force also confirmed that they are investigating and looking to speak with anyone who saw the crash or captured it on their dash-cam.

Information can be reported by calling 101 quoting reference CAD 1969/07Oct.
