Pupils and staff have been evacuated from a north London secondary school following a bomb threat.
Officers arrived at Stoke Newington School in Hackney just before 12pm on Thursday and were doing a sweep of the building to determine whether the threat was legitimate.
Worried parents arrived to pick up their children.
Video posted on social media shows students and staff walking past police cars parked outside the school, where an area was taped off by officers.
Students were taken to a park near the school as police investigated the threat. Hackney Council later announced the school, which has about 1,630 pupils, was closing early for the day.
The Clissold Leisure Centre, across the street from the school, was also shut as the local road was sealed off.
Hackney Police wrote on Twitter: “At 11:55hrs on Thursday, 10 December, police were contacted by staff at a school in Clissold Road, Stoke Newington #Hackney.
“The school had received a bomb threat. The school was evacuated and officers are in attendance.
“Cordon are in place whilst police investigate.”
Hackney Council tweeted: “Stoke Newington School is closing early today following an incident.
“Staff and students have been evacuated, and the police are completing checks of the building.
“Clissold Road and Clissold Leisure Centre are also closed.
“Please avoid the area while the closure is in place.”
Worried parents went to the school to pick up their children after police descended on the area.
One parent wrote: “@MPSHackney @mayorofhackney what’s going on at SNS???? Been told our kids have been evacuated to Clissold Park after an incident in the school but they aren’t saying what!!”
She later added: “Just received a text and I’m on my way to pick up my son.”
Another parent wrote: “Just had a text from Stoke Newington School to say children have been evacuated on police advice…
“Apparently there’s been a bomb threat to the school.
“Hope it’s just a despicable prank and nothing more than that.”
A third parent rote: “I got a message from my child saying the police are outside the school and everyone has to go to the park.”
And another added: “My son said they’re all safe in park but none of the teachers know what’s going on.”
