The video also family friend Paul Williams — whose wife Joanne owned Emry — kicking the tethered animal at rented stables at Glyngwernen Farm, near Llanelli.

Chloe Morgan's solicitor Richard Morgan said: "She has apologised and is remorseful. Some 23,000 people had criticised her actions on Facebook."

The 34-second clip - filmed by a teenage friend of Morgan's, who posted it online "for laughs" - was broadcast to magistrates in Llanelli, Carmarthenshire.

Morgan and Williams, 37, both of Llanelli, admitted causing cruelty to a protected animal and causing unnecessary suffering.

A CRUEL teenage girl who whipped a terrified pony "in a temper" after it threw her off its back walked free from court today after a judge decided not to send her to jail.

Death threats were made against Morgan's caretaker after the video went viral, the court said.

It shows Morgan being thrown from Emry and then whipping the defenseless animal.

Morgan was sentenced to three months in young offenders institution and Williams sentenced to four months' jail, but both sentences were suspended for 12 months.

"Vets who have seen it say that Morgan used excessive brutality on the frightened horse and spat out sperm during the ordeal."

RSPCA prosecutor Nick Devonald said: "The Facebook video sparked outrage when it was posted and has two million views.

But the teacher told the court her actions were "outrageous" and cruel.

When interviewed, Morgan said she sat on the horse for ten minutes before it panicked and she was forced to hit "once or twice."

"Morgan whipped the horse in anger and rage. The animal was extremely scared and panicked throughout the video.

"Vets who saw the video said the horse couldn't escape because it was tied up.

The girls took action after more than 20,000 animal lovers complained about the shocking attack on the four-year-old Emry cob.

"You were not at risk of harm because the animal was tethered. It was a terrible offence and there were no excuses."

Joanne has since given the pony to the RSPCA for rehoming.

After the case, RSPCA inspector Keith Hogben said: "I was horrified and disgusted when I saw what they did with this animal.

They were also disqualified from keeping any animals for eight years and told to do 120 hours' community service.

"I have seen this video so many times but I couldn't look at in court. There was no excuse.

District Judge David Parsons said: "It is plain that this was a vicious assault on a pony for no reason whatsoever.
