Ormiston Primary School was locked down on Thursday after police were called to a nearby incident in which a firearm was believed to have been involved.
Police received a report of a burglary at an address in the Ormiston area at 1.40pm.
“We immediately attended the area and located one offender, who was taken into custody,” Inspector Colin Higson, Counties Manukau East Police said.
“There was a suggestion that a second offender may have been in possession of a firearm, however this has not been substantiated.
“Given the information at the time, Ormiston Primary School was placed into a precautionary lockdown for around 30 minutes given its proximity to the incident.”
A 40-year-old man is currently before the Manukau District Court on a burglary charge.
“Our enquiries remain ongoing into the second offender,” Inspector Higson said.
