Boston High School in Boston, Lincolnshire, was placed into lockdown on Monday, September 14, 2026, after emergency services responded to an incident involving a missing schoolgirl.
The lockdown was introduced as police dealt with the situation around the school. The measures were later lifted, and students were able to resume normal activities for the remainder of the afternoon.
Lincolnshire Police subsequently confirmed that the search for the missing student had ended after she was found.
What Happened at Boston High School?
The incident involved Boston High School for Girls on Spilsby Road.
Police were called after a schoolgirl was reported missing from the school. Officers said the girl was believed to have gone over a gate from the school leading toward Linden Way and Hospital Lane.
Police also said the girl was believed to have a knife with her.
Importantly, police reported that there had been no reports that she had threatened anyone.
The circumstances prompted the school to introduce lockdown measures while emergency services dealt with the situation.
Boston High School Lockdown Lifted
The school confirmed that the lockdown measures were later lifted.
Students were able to resume their education as normal for the remainder of the afternoon after the immediate situation had been brought under control.
During the lockdown, parents and carers were asked not to attempt to enter the school site or contact the school unnecessarily because telephone lines needed to remain available for communication with emergency services.
Students were also instructed to switch off their mobile phones during the lockdown.
The school reassured families that the safety of pupils was its highest priority.
Missing Student Found
The most significant update came later in the afternoon when Lincolnshire Police confirmed that the search for the missing Boston High School student had concluded after she was found.
This meant that the immediate search operation connected with the incident was brought to an end.
No information has indicated that the student threatened pupils or staff, and the police statement did not describe the incident as an attack on the school.
Was There a Threat at Boston High School?
There is no confirmed information indicating that an armed attack or active threat occurred at Boston High School.
The lockdown was a precautionary response while police dealt with the missing-student incident.
Although police said the girl was believed to have a knife, officers specifically stated that they had received no reports that she had threatened anyone.
That distinction is important because the presence of a knife does not by itself establish that a threat or attack occurred.
Were Students or Staff Injured?
There were no reports in the available information of pupils or staff being injured during the incident.
The school also told parents that families would be contacted if their children were ill or injured.
The available information does not indicate that the lockdown resulted from a wider incident involving multiple students or an attacker inside the school.
Police Response
Lincolnshire Police responded to the incident after being contacted by Boston High School.
Officers dealt with the report of the missing student and carried out a search in the surrounding area.
The police response continued while the school remained under lockdown measures.
Once the student was located, police confirmed that the search had concluded.
What Parents Were Told
The school issued an urgent message to parents and carers during the lockdown.
Families were asked not to attend the school site and not to place unnecessary calls to the school because staff needed to keep communication channels open for emergency services.
Parents were also advised not to become alarmed if their children did not immediately answer their phones.
The school said it understood parents’ concerns and was doing everything possible to protect pupils.
