A London school accused of institutional racism is at the centre of a police investigation after alleged death threats against its headteacher.
Harris Academy Tottenham issued a safety notice to staff after its executive principal became the focus of hostility.
A petition calling on the executive principal to quit and alleging discrimination against black students had collected nearly 6,000 signatures as of Friday.
The petition was started last week by Joshua Adusei, a PE teacher at the school for 16 months, who later posted that he had been suspended. This week Adusei was dismissed after a longstanding investigation into alleged gross misconduct. He has appealed against his dismissal.
