Drivers were brought to a standstill on the M25 this morning, after a group of horses got loose on the carriageway in Hertfordshire.
Astonished commuters snapped these pictures, as police chased the animals to get them out of the road.
The horses have now been removed but there are still severe delays on the anticlockwise carriageway between junctions 22 and 27.
