Plain-clothed officers arrived at his home in Sandringham at around 8am today (Thursday, February 19) and arrested him.

The arrest comes on his 66th birthday following allegations made against the former prince after the release of millions of pages of files related to paedophile financier Jeffrey Epstein.

It went in via another gate after waiting 10 minutes.

Five minutes later, a large garage door in the building opened, and two cars could be seen, including the Range Rover.

It drove past the waiting reporters and a photographer was able to take a picture of the former royal trying to lie down on the back seat.
