The boy was struck at Lowestoft Seafront Air Festival, Friday 13th, and it was only while the ambulance team was treating him that they noticed the time - 1.13pm.

The unnamed buy suffered a minor burn and was taken to James Paget Hospital, where he is expected to make a full recovery.

Rex Clarke, who leads the team of St John Ambulance volunteers at the event, said: ‘There’d been very heavy rain all day, but this afternoon we saw a big flash of lightning over the sea and a loud clap of thunder.

'We got a call that someone had been struck by lightning so we immediately sent our paramedics to the scene, followed by an ambulance. Lightning strikes can cause cardiac arrest, but when our volunteers arrived the boy was conscious and breathing.
