Pupils at Greenbank High were told to shelter in their clsssrooms this afternoon after a hoax email made threats to the school.
The content of the email has not been disclosed however OTS News understands that the email is similar to ones received by schools in Liverpool earlier this week.
Police were called to the Hastings Road-based school just after midday, with pupils and staff told to remain in classrooms until an investigation was carried out.
The school alerted parents saying they had taken precautions to keep people safe and that education had continued as normal.
They urged parents not to be concerned and OTS understands pupils are now leaving the school as normal.
Ms Davina Aspinall, Head Teacher at Greenbank High School said: “Like other schools in the region we received email correspondence today of a concerning nature.
“While both Merseyside Police and the Southport Learning Trust believe this correspondence to be a hoax, absolutely no risks were taken and we immediately enacted our shelter mode policy.
“During shelter mode all education continues as normal with added security measures including the locking of all internal doors and windows. Any pupils taking lessons outside were brought indoors as a precaution.
“We immediately contacted parents and carers to alert them to this matter and have maintained communication with them throughout the afternoon.
“The swift support from both Merseyside Police and our dedicated Safer Schools Officer has been fantastic and we would like to place on record our thanks to them.
“Thanks must also go to our staff and pupils for their calm and measured behaviour during this incident and we are incredibly proud of their response, We look forward to welcoming pupils and staff back to school on Monday to resume education as normal.”
