A horse had to be rescued after it was shot through the eye with an arrow in a "wicked attack".

The small white and brown young male may end up losing the eye after the horrific incident.

The animal is being treated by the Royal Veterinary College but is expected to survive.

It was found wandering in a field with the metre-long arrow sticking out of its eye socket in Abbots Langley, Hertfordshire, at around 7pm on Saturday.

RSPCA Deputy Chief Inspector Mel Fisher said: "It seems this poor boy has had a very lucky escape, though the next 48 hours will be crucial.

"The long bow bolt has gone through his eye socket and into his nasal cavity, miraculously without hitting anything vital. It's hoped he won't lose his eye but it's too early to know for sure.

"This was a wicked attack on a friendly and sociable little chap."

Police have appealed for witnesses to the incident to come forward.

Detective Sergeant Dan Stoddart said: "This appears to be senseless, cruel crime and we are doing all we can to find the person responsible."
