Two pupils and teacher hurt in Manchester school stabbing, suspect detained

Counterterror police have taken charge of the investigation into a stabbing at Co-op Academy in Blackley, north Manchester, after two 14-year-old pupils and a 27-year-old male staff member were hurt. The school on Plant Hill Road went into lockdown, and staff detained the suspect quickly to stop any further harm.

Greater Manchester Police said the girl accused of carrying out the attack was arrested on suspicion of Section 18 assault. She was detained under the Mental Health Act and later released back into police custody after assessment by health professionals. All three injured people were taken to hospital, then discharged after being assessed, with officers saying their injuries were not believed to be serious.

On Thursday 11 June 2026, Counter Terrorism Policing North West took primacy for the inquiry after further enquiries. Police stressed that the case had not been declared a terrorist incident and said they were keeping an open mind about the motivation behind the attack. That distinction matters: specialist counterterror officers can be brought in when investigators need extra expertise, wider intelligence checks or a fuller picture of whether an assault may have links beyond a single violent act, but their involvement does not by itself mean terrorism has been established.

Investigators have also been examining social media posts linked to the incident and have warned against speculation as names continue to circulate online. Officers said they were still conducting searches as part of the case, a sign that they are looking not only at the attack itself but also at the online material and context around it.

Chief Superintendent David Meeney said there was no information to indicate any further threat and that local officers remained in the area to support the community. For schools, incidents like this trigger a familiar but painful sequence: lockdown, rapid detention of the suspect, emergency treatment for the injured and then a broader effort to reassure pupils, parents and staff while detectives assess whether the violence was an isolated criminal assault or something that demands a wider counterterror review.
