Exclusive video shows an arrest made after two Auckland schools went into lockdown on Friday.
Armed police surrounded Ōtāhuhu College and King's College earlier in the morning while students were forced to take shelter.
"A suspicious vehicle was spotted and failed to stop for police in Mangere," a police spokesperson says.
"The vehicle was observed by police eagle helicopter to approach Ōtāhuhu College at around 9:30am where three offenders were seen to enter the premise.
"Two offenders were quickly apprehended however a third offender remained outstanding for a period."
The two colleges were put into lockdown while police searched for the individual, who was found hiding in a hallway at the school. No weapons were located on the individual.
A student told Newstalk ZB's Leighton Smith they were secured in a chemistry lab at King's College.
"The school told us just lock all the rooms, and go into the lockdown procedures that we have practiced before," they say.
"We heard helicopters circling the school. There was a SWAT team roaming the school as well.
"What we've been informed by the school is there is a dangerous person around the school and we need to remain in lockdown at the moment."
A spokeswoman for Ōtāhuhu College says it's a police incident and all the students are safe.
