A primary school caretaker accused of sexually abusing young girls is due to appear at Wood Green Crown Court tomorrow.

John Lyon, who works at Saint Andrew’s Church of England Primary School in Churchbury Lane, has been suspended from his job after being charged with sexual offences against a seven and a nine-year-old girl.

Although the alleged abuse on July 30 does not relate to pupils at the Enfield Town school, the 39-year-old was banned from entering a 200 metre radius of the school after appearing at Highbury Corner Magistrates Court on January 29.

He faces three counts of sexual assault, including two against a minor under the age of 13, and one common assault charge.

Chairman of governors Rex Bourne and acting headteacher Christalla Jamil sent a letter to parents dated January 31 telling them about the police investigation.

The letter, leaked to the Enfield Independent, said: “Governors and staff at St Andrew’s School want to reassure you and the community that the safety and wellbeing of pupils is their priority.

“The police have investigated and charged a member of staff at St Andrew’s School of committing serious offences against young people and these charges will be heard in court next week.

“We confirm the investigation did not relate to pupils at St Andrew’s school.”

The letter said when the matter was originally reported to the school, “immediate and appropriate” action was taken.

It said the staff member was suspended from the school and the police and Enfield Borough Council were alerted.

Mr Bourne and Ms Jamil assured parents that along with the council and the London Diocesan Board, the school has “co-operated fully” with police enquiries.

They added: “Enfield Council followed the London Child Protection Procedures to ensure the safety of pupils while the case was investigated.

“Serious misconduct by school staff is rare, but we remain vigilant at all times.”
