A 16-year-old schoolboy has been given a police caution after he was caught on mobile phone footage attacking a 15-year-old Syrian refugee at a school.

West Yorkshire Police said it had investigated whether a racially aggravated assault had taken place at Almondbury Community School in Huddersfield, in October last year.

On Thursday, the force said in statement: "The CPS (Crown Prosecution Service) has concluded that there was not sufficient evidence to charge the suspect with a racially aggravated assault and he was given a caution for a section 39 assault."

The police statement said: "Included in the report received by police, was the video evidence of the incident, which has been widely circulated in the media and on social media.

"The suspect was interviewed by police.

"Upon completion of the investigation, it was reviewed by the youth offending team, the suspect was reported for summons for section 39 assault.

"However, following significant media coverage about the incident, West Yorkshire Police has received further intelligence and evidence and a review of the case was undertaken to investigate whether there was a racially aggravated element to the offence."

The statement concluded: "The victim and his family has been kept updated throughout the process and has been updated on the CPS's decision."
