The incident happened at The Sele School in Hertford on Monday afternoon during a district football tournament, with “several people” affected.
Headteacher Chris Quach posted on the school’s Facebook page: “There was a district football tournament organised by an external body at The Sele School. Sadly, a young boy from another school and an adult was struck by lightning during this event.
“They have been taken to the hospital. Myself, the entire staff at Sele and wider community would like to thank emergency services, the community and our first aiders who were quick to respond whilst waiting for emergency services.
“Our good wishes and thoughts are with the people who were injured.”
It comes amid a yellow weather warning covering Hertfordshire for thunderstorms, which is in place until 2am tomorrow (October 3).
