A security alert in Cambridge Avenue area of Ballymena has ended.
Army Technical Officers examined a suspicious object discovered in the area and a number of items, including a BB gun, have been removed for further examination.
All roads have now reopened to traffic.
Earlier Cambridge Avenue was closed and Cambridge House Grammar School was evacuated.
Parents had received an "urgent" message telling them to arrange collection for their child as soon as possible.
It said: "As a precaution we are evacuating the school and would request that you arrange to collect your son/daughter as soon as possible a parking in the bay outside school.
"When you arrive at school please take instructions from the person at the gate."
Mrs Elma Lutton, principal of Cambridge House Grammar school said pupil safety is of "extreme importance" and "at no time was this compromised".
Mrs Lutton said: "Following the discovery of items on the grounds of the school, the PSNI were contacted immediately.
"The school was then evacuated, as a precautionary measure, on the advice of the PSNI. The safety of pupils at the school is of extreme importance and at no time was this compromised”.
Councillor Timothy Gaston said the pupils were moved to the assembly point at the back of the school.
This is the third time in the past two months that a security alert has been sparked in the area.
Homes were evacuated on March 21 after the discovery of a suspicious object close to the school.
That device was examined by Army Technical Officers and declared to be "an improvised firework".
It was removed for further examination.
Most recently an alert on April 7 was also found to be caused by a firework.
