The teacher could not believe what he overheard. The "visiting" imam was launching into a tirade against the Jews and Americans that bordered on the ludicrous.
But then came the clincher, he recalled. "The imam told the students that the Jews were putting poison in the bananas and they should not eat them."
In one case a non-Muslim member of staff was told to remove a crucifix from the dashboard of a car parked in view of the students and a female Hindu teacher was ordered to remove marriage jewellery.
The teacher, who was dismissed from the school because she was "over qualified", is now employed at a Christian faith-based school.
She says she has no regrets about leaving. "The atmosphere at the school was unhealthy," she said. "When you asked children to write about their favourite hero, they nearly always wrote about Osama bin Laden."
Poisoning the minds of the future and molding suicide bombers.
