The police force said: “Emergency services are on scene and the school grounds currently remain closed."

“Granville Road is closed from the tram stop to Fitzwalter Road, and we are urging people to avoid the area while emergency services carry out their work.

“We would like to reassure parents of pupils that we do not deem there to be a further risk at the school and further updates will be shared when possible.”

Images shared on social media show an air ambulance landing near the school while parents congregate at the police cordon.

The closure marks the second time the school has gone into lockdown within a week.

It is the second time that the school has gone into lockdown in a week.

According to reports, headteacher Sean Pender sent a message to parents on January 29, saying: “The reason for the lockdown was due to threatening behaviour between a small number of students where threats were made of physical violence.”

One parent said that they were keen to get their child home after they heard about rumours about what had happened.

"Until we get kids out and get home and speak with them to find out more, we cannot say more things about it," they told the BBC.

"Kids were getting panicked, we had a lot of calls, even now," they said.
