Welford was one of 21 schools inspected by Ofsted earlier this year during its investigations into the so-called Trojan Horse controversy
The head at one of the schools in Birmingham at the centre of the "Trojan Horse" controversy has been confronted by a group of parents.
Jamie Barry, the head at Welford Primary School, had to be escorted from the building "for his own safety", according to a colleague.
The parents were unhappy about elements of the school's curriculum, the city council said.
The incident happened during a parents' forum being held at the school.
Welford Primary School was one of 21 schools inspected by Ofsted earlier this year during its so-called "Trojan Horse" investigations.
In March an anonymous and unverified letter sent to Birmingham City Council claimed that there was a "Trojan Horse" conspiracy to take over governing bodies and create a school culture more sympathetic to their hardline Muslim religious ethos.
Birmingham City Council and National Association of Head Teachers (NAHT) both appealed for calm after the confrontation at the school.
Sally Taylor, from the council said: "We are concerned that parents are objecting to elements of the equality and diversity agenda which forms part of the personal, social and health education (PSHE) curriculum."
She said it was not acceptable for parents to "pick and chose between aspects of this agenda".
The council was providing direct support to the head and the chair of governors, she said.
Russell Hobby, general secretary of the NAHT, said: "The incident shows that tensions between schools and communities can run high in the wake of Trojan Horse."
