Two teenage boys have been charged over a playground happy-slapping fight which was filmed on a mobile phone.

A 16-year-old boy was left with a broken arm following the violence at Patcham High School in Brighton on January 29.

One pupil has now been charged with assault occasioning grievous bodily harm while a second boy, also aged 16, has been charged with aiding and abetting the assault.

Both boys were released on bail to appear at Brighton Youth Court on Friday.

Police are still investigating a second attack outside the gates of the school in which a 16-year-old girl was beaten up.

The girl was punched and clumps of her hair were pulled out last Wednesday.

A friend of the victim's family said they believed the incident had been filmed on mobile phones.
