A youth with a BB gun has been found in Cambridge after schools were locked down due to concerns about a man with a weapon.

Police were called to Swayne Rd at 10.40am after receiving a report of a male with a weapon, a police spokesperson said.

Officers had since found a young person is possession of a BB gun.

Schools had been advised they could come out of lockdown, the spokesperson said.

Cambridge East school told parents at 12.03pm they had come out of lockdown and all students, staff and people on site were accounted for.

'Everyone did extremely well and responded to instructions.”

Earlier, Cambridge Middle School said in an email to parents that the school was advised to go into lockdown because of an incident 'at a neighbouring school”.

'Please do not come to school or phone the school as you will not be attended to as your child's welfare and safety is our priority,” it said.

Meanwhile, in a text to parents, Cambridge High School said 'because of police instructions regarding a local situation, the school has gone into lockdown”.

'All students are safely locked in classrooms and will remain there until the police give the all clear.”
