Three teenagers have been sentenced for what a judge has described as a "truly shocking and barbaric" attack on a girl on a County Down pier.

The girl, who was 16 at the time, was punched 30 times and had her head stamped on in Bangor in April 2018.

On Tuesday at Newtownards Crown Court, Cora Campbell and William Boyd, both 19, with addresses at Hydebank Prison, were sentenced to 32 months.

They will spend half of that term in prison and the rest on licence.

A third defendant, who is 17 and cannot be named, was told she must carry out 120 hours community service and write a letter of reflection to the victim.

The attack on the girl was filmed on a mobile phone and posted on social media.

The court was told that Campbell grabbed the victim by her hair and attacked her.

'Traumatic ordeal'

When the girl was lying injured on the ground, Campbell returned and attacked her again.

As well as being punched and stamped on, the victim was dragged to a fountain where her head was held under water.

The court heard Boyd goaded a gang of about 15 people by shouting: "Break her nose."

He also poured beer and vodka into her eyes and throat, something the judge said was akin to waterboarding.

Speaking after Campbell and Boyd were sentenced, Det Con Hughes of the Police Service of Northern Ireland said the assault was "clearly a traumatic ordeal" for the victim.

"I hope it gives them some measure of comfort that the perpetrator has been found guilty."
