A group of teenagers filmed themselves on Snapchat feeding cigarettes to a horse.

The gang were seen crowded around the horse on a farm in Surrey on Tuesday night laughing as one of the group fed the animal several unlit cigarettes.

Farm owner Moya Hayward and son Josh Cummings say they have had problems with the gang who have terrorised their animals for years.

They claim the teens have chased their horses, thrown stones and attacked them with bottles.

Moya says something needs to be done to protect their seven horses and other animals on their farm.

It could make the horses very ill and their parents aren't going to pay the bill. There were 15 to 20 youths out there videoing it, laughing about it, and they are as bad as each other. I love my animals and if anybody touches them they are asking for trouble. We have had all sorts happen to them. We have had bottles thrown at the horses, stones thrown and we just don't want the kids around. A day doesn't go by that I am not having to scream at kids to get out of the field and get away from the horses. You then get the bigger boys who think it's acceptable to throw stones at horses and then of course the younger ones think it's OK to do the same. Moya Hayward

The farm in Banstead, Surrey, has a variety of animals including chickens, sheep and pigs, but the horses are the animals abused the most.> Moya's son Josh, 23, helps his mum run the farm and sees the gang almost every night terrorising the farm animals.> On Tuesday night Josh ordered them off the farm and shortly afterwards he managed to get his hands on the video.
