Over 400 school students demonstrated outside Carlton Bolling College, Bradford, on Wednesday of last week.
They were protesting against the suspension of support worker Asif Khan.
It is widely believed that he has been picked on for his support for Palestine. Demonstrators carried Palestinian flags in support.
Many suspect Asif is being victimised because he is the brother of the recently removed chair of governors, who was targeted by the government’s “Trojan Horse” witch hunt.
Campaigners have circulated a letter to parents asking them to call for the suspension of the headteacher.
