Residents held a candle-lit protest at a school's open evening alleging racism amongst pupils.
But the headteacher of Thornhill Community Science College, Jonny Mitchell, said the claims were unsubstantiated.
Around 12 protesters met outside the school in Valley Drive as it held an open evening.
Organiser Shaun Maddox said: "There is no community cohesion here at all. There seems to be a barrier between the white community and the Muslim community."
