A video showing an attack on the girl's brother was widely shared.
The sister of a refugee pupil shown being attacked in a widely shared video was also attacked by other pupils in a separate incident, their family has claimed.
The footage was claimed to be filmed at Almondbury Community School in Huddersfield.
Earlier, a video showing a 15-year-old Syrian refugee being attacked at the same school was circulated on social media.
West Yorkshire Police said a 16-year-old boy is to be charged with assaulting the boy.
