Police said no risk was posed to any individual on site.
Officers were also called to the Duke of York’s home after a woman reportedly talked her way into his mansion on April 19.

The woman had reportedly arrived to Windsor in a taxi - and had even persuaded the duke’s security guards to pay her fare.
Police said the woman was stopped and later sectioned under Section 136 of the Mental Health Act.
