Two horses broke loose after a horsebox was involved in a crash on the M25 in Surrey, leading to tailbacks on a busy summer holiday weekend.
The collision between the horsebox and another vehicle, possibly a white HGV, happened between junctions 9 and 8 at around 9.40am.
Traffic officers at Surrey Police said there were no human injuries. One of the two horses suffered some injuries but was still able to walk.
