Counter-terrorism officers are leading an investigation into a stabbing at a school in Manchester, police have said.
Two pupils, both aged 14, and a male member of staff, 27, were injured in a knife attack at the Co-op Academy in Blackley on Tuesday morning, according to Greater Manchester Police.
On Thursday evening, the force said Counter Terrorism Policing North West is now leading the investigation with support from Greater Manchester Police after further inquiries.
At this time, it has not been declared a terrorist incident, police added.
A 14-year-old girl who was arrested on suspicion of assault and later detained under the Mental Health Act has been released to police custody following an assessment by health professionals.
All three who were injured have been released from hospital and suffered no serious injuries.
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.”
Staff at the school in Plant Hill Road were quick to detain a girl after the incident to ensure no further harm came to students or staff before officers arrived shortly afterwards, the force previously said.
It is understood that the school placed itself in lockdown after the incident.
