Statement on behalf of CTPNW - Update following incident at school in Blackley

Following an incident at a school in North Manchester earlier this week, we can confirm that Counter Terrorism Policing are now leading the investigation.

Officers were called to reports of a stabbing at a school on Plant Hill Road, Blackley, on Tuesday 9 June 2026.

As a result of further enquiries, Counter Terrorism Policing North West have now taken primacy for the investigation with the support of Greater Manchester Police.

Searches relating to the investigation remain ongoing and counter terrorism detectives are keeping an open mind to the motivation of the attack.

A 14-year-old girl was arrested on suspicion of Section 18 assault and detained under the Mental Health Act. Following an assessment by health professionals she was released to police custody.

The three people who were injured have all been released from hospital and thankfully suffered no serious injuries.

At this time, it has not been declared as a terrorist incident.

Chief Superintendent David Meeney, Commander for Manchester, said: “Our local detectives have been investigating this incident at pace ever since we arrested a schoolgirl suspect on Tuesday morning. She remains in custody in Manchester.

“This has included ensuring the suspect is checked by health professionals to make an assessment while under the Mental Health Act, and to explore all available evidence to understand why this incident took place.

“Since our last update, further information has come to light that we have made Counter Terrorism Policing North West aware of.

“I know this update will only continue to make our local community concerned by Tuesday’s events.

“There is no information to indicate any further threat, and our local officers continue to be in the area. We are here to listen and to act, so please speak to our officers with any concerns.”
