The Crown Prosecution Service is deciding whether teenagers interviewed by police in connection with a brutal filmed attack on a teenage boy will face trial.

The teenager was robbed and left with bruising to his face after being attacked in a park of Hayling Road, South Oxhey, on February 17.

The beating was filmed on a mobile phone.

No one has been arrested in connection with the incident but Hertfordshire Constabulary says findings of its investigation have been sent to the Crown Prosecution Service.

A police spokeswoman said: "Seven teenagers have been interviewed out of custody in connection with an incident in which a 16-year-old boy was allegedly assaulted.

"It was reported that on February 17 this year, the boy was assaulted on a playing field off Hayling Road in South Oxhey. He was left with bruising and swelling to his face.

"The teenagers interviewed are two 17-year-old boys, a 17-year-old girl, two 15-year-old boys, and a 14-year-old girl - all from South Oxhey. A 15-year-old boy from Hemel Hempstead has also been interviewed.

"The case file has now been submitted to the Crown Prosecution Service and is currently being reviewed.

"The victim and his family are aware and will continue to be supported by officers as the case progresses."

On June 19, three teenagers were given referral orders following a separate filmed attack on a 14-year-old girl in Henbury Way, South Oxhey, on March 3.

All three defendants, who cannot be named for legal reasons, 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.
