A teenage boy has been stabbed near his school in south-east London.
The secondary school, in Plumstead, was placed on lockdown after the boy was knifed nearby on Thursday afternoon.
The victim, believed to be 16, was rushed to hospital following the attack shortly after 3.20pm.
He suffered a stab wound to his shoulder and remained in hospital. His condition was not life-threatening, Scotland Yard said.
Police and paramedics had been scrambled to reports of a man armed with a blade in Griffin Road.
Plumstead Manor School, which is located in the nearby Old Mill Road, confirmed the victim is one of its Year 12 pupils.
It said the boy was stabbed at a bus stop in the local area by an attacker “unknown to the school”.
Students were let back into the premises before the entrances were locked as police surrounded the area, the school said.
The school wrote on Facebook: “After school today at a bus stop in the local area a young man who is in Year 12 at Plumstead Manor School was stabbed by an attacker unknown to the school.”
It said the premises was placed on lockdown for about 30 minutes while the police made sure the area in the vicinity of the school was safe.
“Once this was confirmed we released students, making contact with parents and carers where necessary to make sure all our young people reached home safely.”
“The school will be open as normal tomorrow, and we will offer support and counselling to anyone who has been affected by this.”
No arrests have been made, Scotland Yard said.
“Police were called to reports of a man armed with a knife in Griffin Road,” a spokesman for the force said.
“A teenage boy, believed to be 16 years old, suffered a stab wound to his shoulder. His condition is not life threatening.”
