Student Olivia Wynn took a picture of the galloping animal from the passenger seat of the car she was driving back from a day trip in York in with her mum, Deborah just by junction 27 near Birstall, West Yorkshire.
All lanes were affected for almost one hour when the horse hurtled through a fence near junction 28 in Tingley and attempted to travel the wrong way along the east-bound side at evening rush hour.
Police say they have no idea where the animal came from, or who it belonged to...Gosh, what a puzzle! Can't you check the tattoo or microchip?
No. Silly question, I guess.
Inspector David Peach, of West Yorkshire Police, said: 'We tried to corral the horse to safety but whilst it had been running free, it had caused severe damage to its leg and when it was finally rescued, it was in considerable distress.
'The only humane option was to put it down. The only right thing to do was to put it out of its misery.'One assumes that, because you were presumably closer, you managed to accomplish this with less than nineteen bullets this time?
In a Twitter alert, West Yorkshire Police RPU, who were called to the scene following calls from several bewildered motorists, said that it was 'running all over the place' and warned drivers to be careful. Police officers stopped lanes and slowed traffic until they were able to approach the horse.
They are now trying to arrange for repairs to be made to the fence to prevent it from escaping again.Wha..?
Hang on, I thought you said you'd no idea where it came from? And that you destroyed it?
