A PE teacher who was supervising an athletics session at a Kent school when a 14-year-old boy became impaled by a javelin has resigned.
Edd Stuckey was airlifted to hospital after the incident at Norton Knatchbull secondary school in Ashford on 19 May.
Head teacher Susanne Staab said the schoolboy was "recovering well".
She said against established practice, the javelin had been used as a finish marker with the tail end pointing upwards as pupils completed a run.
'Wind blew javelin'
Ms Staab added: "Why the javelin was used on this occasion is part of the investigation, but the member of staff who was leading the lesson has resigned with immediate effect.
"From speaking to staff and students it appears the wind blew the javelin at an angle and in doing so, Edd made contact with the tail end of the javelin as he completed the run.
"We are determined to ensure that no such accident can happen again in the future."
Following the incident, the teenager was taken to a major trauma unit at a London hospital where he had surgery.
