Four people have been arrested after images of Donald Trump with convicted sex offender Jeffrey Epstein were projected onto Windsor Castle - where the US President is set to be hosted by King Charles during his state visit to the UK.
Trump arrived at London Stansted late on Tuesday for an unprecedented second state visit, and will be greeted by Charles on Wednesday for a day of pomp at Windsor Castle.
Earlier on Tuesday, protesters unfurled a massive banner featuring a photograph of Trump and Epstein near Windsor Castle, and later projected several images of the two onto one of the castle's towers.
Thames Valley Police later said four adults were arrested on suspicion of malicious communications following an “unauthorised projection” at Windsor Castle, which they described as a “public stunt”.
Chief Superintendent Felicity Parker said: "We take any unauthorised activity around Windsor Castle extremely seriously.
“Our officers responded swiftly to stop the projection and four people have been arrested.
“We are conducting a thorough investigation with our partners into the circumstances surrounding this incident and will provide further updates when we are in a position to do so.”
Political campaign group Led By Donkeys shared an image of the stunt to Instagram with the caption “Hey Donald, welcome to Windsor Castle”.
The four people remain in custody, the force said.
It comes after Democrats in the US House of Representatives on September 8 made public a birthday letter Trump allegedly wrote to Epstein more than 20 years ago, though the White House has denied its authenticity.
The letter was also projected onto the castle, along with pictures of Epstein's victims, news clips about the case and police reports.
The release of the letter has brought renewed attention to an issue that has become a political thorn in the president's side.
Trump was friends with Epstein before becoming president but had a falling out with the former financier years before his death in prison in 2019.
The birthday letter contained text of a purported dialogue between Trump and Epstein in which Trump calls him a “pal” and says: "May every day be another wonderful secret." The text sits within a crude sketch of the silhouette of a naked woman.
