Thieves have stolen a single lamb from a learning-disability farm in Stapleton, Bristol.

The four-day-old lamb, which was part of a set of twins, was taken from Elm Tree Farm last week (Tuesday, April 19).

Elm Tree Farm, managed by Brandon Trust, is a social enterprise and care farm, that provides support, training and work to adults with disabilities and autism.

The farm took to Facebook to share their story:

"Unfortunately, today's post is not a positive one, and one which deeply saddens us.

"It was heart-breaking when we arrived this morning to check on our little ones and discovered that someone has cut through one of our stock fences into the sheep field and stolen one of the twins.

"The theft has left the mother Soay and her remaining lamb very distressed, searching for the lost lamb. The gap in the fence also left the other sheep vulnerable."

Because the lamb was so young, its chance of survival without the mum, the farm said, is slim.

"As a farm team we're shocked and upset that someone would do this," it added.

The farm is appealing to anyone with information that might help to call the police, or Elm Tree Farm itself.
