Uxbridge High School has moved to reassure parents after its former principal and his deputy were found to have failed to protect a 13-year-old pupil from abuse at the hands of a teaching assistant.

Peter Lang, ex-head of the school, and previous vice-principal Judith Barton failed to tell police about serious allegations that could have helped police catch now convicted paedophile Kevin Sempers. The both subsequently resigned.

But the pair can now return to work after a National College of Teaching and Leadership tribunal decided there was no need to ban them from the profession.

Peter Lang resigned as Uxbridge High School principal in 2014

Three years have passed since the incident, and Uxbridge High School now has a new principal, Mr Nigel Clemens, who has been in post since late 2014.

A spokesman for the school said: “Our main priority continues to be the welfare and safety of all of our students at all times.

“In the three years since 2013, the school's safeguarding procedures have been confirmed by independent auditors as robust and go above the standards expected.”

Decathlete Sempers, 30, originally from Scunthorpe, competed in the Commonwealth Games in Delhi in 2010.

He was jailed for 18 months in December 2014 and placed on the sex offenders' register for 10 years after admitting two counts of engaging in sexual activity with a child.
