A 16-year-old boy has been reported for summons for assault after a video showing a boy being attacked was shared on social media.
The boy, 15, is shown being dragged to the floor at a school in Huddersfield before water is poured into his face.
The video was filmed in a lunch break at Almondbury Community School on 25 October, West Yorkshire Police said.
The force said the older boy, who cannot be named for legal reasons, will appear at Youth Court “in due course”.
Police initially said they were investigating the incident after a report of racially-aggravated assault.
An online fundraising page set up to help the 15-year-old boy and his family has so far raised more than £50,000.
