This marks the second time in less than a week All Saints’ has been locked down, after staff and pupils were given the ‘stay put’ order on January 29 over ‘threats of violence’ between a ‘small number of students.’
This first incident led to those involved being ‘escorted off the premises’ with no violence or injuries reported.
Headteacher Sean Pender said in a message to parents that today’s the incident involved two students.
He said: ‘I am writing to inform you that today we have dealt with an extremely serious incident here in school resulting in us going in to a lockdown procedure.
‘The incident involved two students, one of whom we believe has been seriously injured. All other students are contained and safe.
‘The police and paramedics are present in school. Once the police allow us to, we will be releasing all students from school.
‘I understand the level of anxiety you will be feeling without knowledge of the nature of the incident but at this time I have limited information to share with you whilst we have police and paramedics on site.
‘I will endeavour to update you with as much information as possible at the earliest opportunity.

‘We ask for your prayers and support at this time.’
A parent, who asked to remain anonymous, told The Star today: ‘This is frightening to hear so soon after a previous incident and I hope and pray everyone is okay and the incident is resolved peacefully.
‘Now is not the time for recriminations but the school will have some serious questions to answer in the coming days.’
Amaan Ahmed, one of the managers at Castle Asian Community Trust and Mosque in nearby Norfolk Road, said: ‘This area has seen an increase in crime recently. Cars are being stolen and vandalised, there has been an increase in anti-social behaviour – it is quite rampant in the area.
‘It is concerning, especially being a community centre.
‘We provide facilities for people to pray and we have children who are afraid. We are very saddened to hear the news from the school.’
A 2023 Ofsted report rated the school, which had 1,398 pupils at the time, as ‘good’.
Inspectors found that most pupils behaved well, and they said ‘a strong ethos of warmth and respect pervades this school’.
