A supply teacher has been escorted off a school premises after claims he made a racial slur towards a 12-year-old pupil.
Manchester Health Academy in Wythenshawe say they are investigating the allegations, which were raised after a video was circulated on social media.
Headteacher Kevin Green said the academy are taking the complaints 'very seriously.'
A parent, who wished to remain anonymous, told the Manchester Evening News her son had witnessed the incident on Thursday morning.
She says her son, who is in year eight, was left 'upset' and 'distressed' by the racial language, alleged to have been used by the teacher.
"I was going to meet my son for a meeting with the headteacher when I found out about it," the parent said.
"On the way out I was told he had witnessed an incident and that one of the supply teachers had been escorted from the premises."
She added: "When I asked my son what had happened later, he told me the supply teacher had made a racist comment about his friend.
Both boys are of Asian heritage, the parent said.
She said her son had been filming himself and a friend playing with a rubber, which appeared to hit the teacher on the hand.
Following this, claims were made that the teacher used racially abusive language towards the boys.
"My son ran out the room and went to tell another teacher what had happened," the parent said.
"He is really upset and distressed about what happened, and says he does not want to go back to school.
"It's awful, you don't expect that from anyone let alone a teacher."
