A school went into lockdown after a person was seen acting suspiciously outside the building.

Pupils at Crestwood Community School were kept inside for their lunch break today.

Police were called to the school’s Shakespeare Campus at 12.15pm after the alarm was raised.

Head teacher Krista Dawkins said she made the decision to prevent students from leaving the premises.

She said: “We are now out of lockdown after we had youths that we deemed as being a nuisance on the educational premises.

“As it was during a break time, the police were called, and we deemed it best to enter lockdown.

“The trespassers have been taken back off site and we are working with our community policing team.

“I took the decision to enter lockdown because it was break time and happened outside.”

It was reported to police that a person sought to gain entry to the premises but were not successful in their efforts.

A spokesperson for Hampshire Constabulary said: “As part of our enquiries, a 15-year-old boy from Eastleigh was detained by officers and staff; being returned to an alternative address and spoken to by local officers.

“To reassure the community, there is no perceived further risk to pupils and staff at the school, nor the wider public.

“Officers will be conducting high-visibility patrols in the area. If you are concerned, please do speak to our officers while they are on duty.”

The school received a 'good' rating from Ofsted earlier this year, with inspectors praising its curriculum and dedication to its pupils.

The report found that it has a "strong" stance on improving attendance and pupils like and trust their teachers. 

Ofsted also highlighted the wide range of extra-curricular activities and clubs that Crestwood offer to pupils, adding: "Teaching and support staff, including those in the early stages of their careers, are proud to work at the school."
