A school bus with up to 52 children on board has overturned in Co Cork.

Update at 2pm: James O’Donoghue, principal in Bishop Murphy Memorial School in Fermoy, was travelling on the road when a schoolbus carrying 52 children hit a tree and overturned a short distance behind. “It was a huge fright,” he said.

“I did not know what was going on at first as I could not see the bus as I was in a line of traffic but it was an awful fright altogether. It was passers-by who told me what had happened.

“There was an acute bend on the road. Thankfully it was not any worse.”

No pupils from Bishop Murphy were on board.

Gardaí and school principals are also liaising to record the exact numbers of pupils from the respective schools who were on board at the time.

Update at 12.50pm:

One pupil is understood to have suffered a broken leg.

It is understood the coach hit a small tree as it slid into the field and overturned.

The emergency exit door at the rear of the vehicle was blocked and the driver smashed the front window to allow the pupils to escape.
