A 12-year-old girl has died after being hit by a rugby ball during a PE lesson at an Essex school.
Leonie Nice was catching the ball during a lesson at Woodlands Comprehensive School in Basildon on Tuesday when she was hit in the chest and fell over, appearing to have a fit, Essex County Council said.
