Police are hunting a man who triggered a lockdown at a Sydney high school

A police operation is underway at a Sydney high school after a staff member was challenged by a teacher on school grounds.

There were earlier reports that the man had been carrying a gun.

Sydney Boys High School, near Moore Park between Cleveland and South Dowling Streets, was placed into lockdown for a short period of time until the safety of all students and teachers could be assured.

News Limited reports that some students congregated in a nearby park after police told them to “drop everything and go”.

A police spokesperson confirmed with Business Insider that a police operation began just after 2pm today after reports that an armed man was seen leaving the school.

“The school has been put into lockdown as a precaution,” he said, “all children at the school are accounted for. There are no reports of injuries.”

The man was later seen leaving the school grounds. Police from Surry Hills Local Area Command continue to search for him.

He is described as being 20-years-old, 175cm tall with short dark hair and was wearing light blue jeans, a white shirt and a pair of hiking or work boots.

The man was carrying a grey shopping bag when last seen.

Police have now confirmed that at no time was a firearm sighted.
