A teenager has denied wounding a teacher who was stabbed in a school corridor in Gloucestershire,

The 15-year-old boy, who cannot be named for legal reasons, appeared at Cheltenham Magistrates’ Court where he pleaded not guilty to wounding with intent.

However he pleaded guilty to possession of a bladed article on school premises.

Teacher Jamie Sansom suffered a single stab wound in the incident in a corridor at Tewkesbury Academy on Monday morning.

He was taken to Gloucestershire Royal Hospital and later discharged. He was said to be “recovering well”.

The academy was locked down and two neighbouring schools were also asked to shut their doors as a “precaution” following the incident, Assistant Chief Constable Richard Ocone of Gloucestershire Police said.

No one else was injured.
