A nursery has gone into lockdown after two people got onto the roof of the building.
Police confirmed a man and a woman were involved in the incident, which is taking place at Dawn to Dusk Nursery in Swanley.
They were called to the scene just after 1pm.
A police spokesman confirmed officers managed to talk the woman down to safety.
But they remain at the scene and have closed St Mary's Road as a precaution.
The woman was not arrested.
