An investigation into how a pupil came to have a knife in a primary school has concluded it was most likely brought into school.

The school also confirmed police will now be brought into the school to provide 'personal safety' workshops.

In September, a pupil at Phoenix St Peter Academy in Lowestoft was found with a craft knife in a classroom.

The knife was confiscated and the blade was not revealed at any point and no-one was harmed.

In response to the incident the school launched an investigation which has since been completed, concluding the knife was 'most likely' brought in from outside the school.

The investigation involved the school interviewing children, staff and parents about the incident and establishing whether there were any craft knives on the school premises.

In a statement, a spokesman for Phoenix St Peter Academy said: 'In line with our processes we have carried out a full and thorough investigation, involving interviewing children, staff and parents.

'We do not have craft knives at school and so the investigation has concluded that it was most likely bought in from outside.'

She added: 'This is a highly unusual situation and although no one was harmed in any way, we have taken the opportunity to organise a series of workshops by the local police on personal safety.'

Parents had found out about the incident through a letter sent by headteacher Nadia Paczuska on September 14.

In it she wrote: 'This of course may be very alarming to parents and I want to assure you that it is highly unusual and that we take the safety of children very seriously.'

A spokesman for the school said at the time: 'We take the safety of our children extremely seriously and are conducting a full and thorough investigation into how this happened, with support from REAch2, children's social care and the police.

'We want to reassure parents that we have taken steps to ensure that this never happens again.'
