A private school has reviewed its policies on safeguarding pupils after a maths teacher was jailed for grooming a 15-year-old girl.

Dr John Wunderle, 35, was employed as a maths teacher at £15,000 a year Bancroft's in High Road, Woodford Green before being suspended in June when he was caught half-dressed by the pupil's parents in her bedroom. 

He was jailed for four years and placed on the Sex Offenders’ Register indefinitely at Snaresbrook Crown Court on Friday after previously pleading guilty to five counts of sexual activity with a child.

The intimate relationship started earlier this year but he had been offering private tuition in preparation for the girl's GCSE's at her home since September 2013.    

He admitted to having sex with the teenager between March and June this year, two counts of sexual touching and one count of kissing.   

The school has taken measures to update its safeguarding policies in light of the events and headteacher Mary Ireland has promised it will never happen again.  

Mrs Ireland said: "The school has reviewed its policies in light of the events with the help of the Independent Schools Inspectorate. 

"The policies have been updated in line with ‘Keeping Children Safe in Education’ which was published last term. 

"Our policies are robust and were followed correctly, but there had been no previous indications that this could happen. 

"The year group of the pupil involved were offered independent counselling to allow them to express any concerns that they might have.

"As you can imagine, the whole community is now extremely vigilant to ensure that this never happens again. 

"The school was complimented on its excellent Pastoral system in the last inspection, which provides a network of support for the pupils to ensure that they feel safe and secure at school."
