A science teacher was being questioned by police on suspicion of attempted murder Thursday after a 14-year-old boy was left with serious head injuries after an alleged attack at his school.

Peter Harvey, 49, is also being questioned about alleged assaults on two other pupils, believed to be a boy and a girl, also 14. He was arrested Wednesday at All Saints’ Roman Catholic School in Mansfield, England.

Police were called to the school after paramedics arrived to find the 14-year-old student lying in a pool of blood at the entrance to a classroom in the science building.

Detective Superintendent Adrian Pearson, of Nottinghamshire Police, revealed details of the allegations at a press conference outside the school Thursday. He said the two other students were allegedly assaulted during the same incident in which the teenager was hurt, though less seriously.

The boy was taken to King’s Mill Hospital in the town but his condition deteriorated during the afternoon and he was transferred to a specialist unit at the Queen’s Medical Centre in Nottingham. Nottinghamshire County Council, the local education authority, said the boy’s condition had improved slightly overnight.

Mr Pearson said: “As you know, an ambulance was called at just after 11 a.m. yesterday morning. Subsequently, a 14-year-old boy was taken to hospital having sustained serious head injuries."

“A 49-year-old local man is in custody at the moment and it is appropriate to say he has also been arrested on suspicion of assaulting two further children at the time of the incident."
