A 15-year-old boy from Rickmansworth filmed two girls attacking another girl while encouraging them to carry on the assault.
The boy and the two girls – both from South Oxhey – appeared before St Albans Youth Court on June 19.
The two girls each pleaded guilty to a charge of assault occasioning actual bodily harm (ABH) and the boy pleaded guilty to a charge of intentionally encouraging/assisting the commission of an either way offence.
The court heard how on Sunday, March 3, the victim was lured to a children’s playground on Henbury Way in South Oxhey after being contacted by one of the female defendants.
Once she was there, the two 14-year-old girls confronted her and began physically assaulting her by kicking and punching her. When she fell to the ground, they continued to attack her.
While this was going on, the boy filmed the attack on his mobile phone and was heard to encourage the girls to continue the assault.
The footage, which was played to the magistrates in court, showed the victim bleeding from the nose and holding her arms up to protect herself.
It is thought they conspired to carry out the attack after a minor disagreement occurred between themselves and the victim on a previous date.
All three defendants were given a 12-month Youth Referral Order and a 12-month restraining order which prevents them from making contact with the victim. They will also have to pay £500 each in compensation to the victim.
They will appear before a panel made up of community volunteers in due course who put together a contract of conditions as part of their referral order, which the teenagers must adhere to.
