A Suffolk secondary school has issued an update after it was forced to go into lockdown yesterday.

Police received reports of three young males in Wells Hall Road next to Thomas Gainsborough School (TGS), in Great Cornard, Sudbury, at around 2.45pm on Friday. 

Both TGS and Wells Hall Primary School was put in lockdown as a precaution while officers attended the area. 

Helen Yapp, Headteacher at TGS, has since confirmed that nobody gained access to the school site during the incident. 

She said: "Students stayed with their class teachers, and in line with our usual policies, students were instructed not to use their phones.

"When we heard from the police that we could allow students to leave we did so.

"At no time was there any unauthorised person on the school site, and our school community was not at any risk."

At about 3.40pm TGS said the police had made them aware that the area was safe and students could leave the building.

No arrests have been made.
