An eccentric great-grandmother who sent a letter to the headmistress of a top Islamic girls school claiming ‘all Muslims worship Satan’ has landed herself with a criminal record for ‘causing harm.’

Devout Christian Rose White, 68, typed the three page note saying: ‘I was saddened to see you enforce full Muslim dress and force pupils to accept the role of Satan’ after seeing photos of pupils dressed in burkhas on the school’s website.

Accompanying the letter was a 23-page cartoon-strip booklet titled, ‘Is Allah Like You?’ showing a Muslim family with a cruel father who then becomes kind after turning to Christianity.

The letter said schools would ‘have a nice future under Jesus and not Satan or Mohammed or whatever they call him’.

Police were called in after Mona Mohammed, headteacher at the 232 pupil Manchester Islamic High School for Girls picked up the letter when pupils and staff returned after a half term break.

Ms Mohammed who has been head at the £5,000 a year school since 1991 was said to be ‘deeply alarmed’ by the contents of the letter and felt it was a personal attack on her and her school.

White, a retired mill worker from Greetland in Halifax, later claimed she became a Christian in 2014 following repeated callings from God and saw it as her ‘duty’ to tell Muslims to convert to her religion.

At Manchester magistrates court she denied wrongdoing but was convicted of sending an indecent or grossly offensive letter and was ordered to carry out 100 hours of unpaid work.
