An investigation into the security breach is underway after police removed the intruder, who talked his way into the Victoria Barracks. On April 26, while the monarch was away from nearby Windsor Castle celebrating her 96th birthday at her Sandringham estate, a man dressed as a priest claimed to be a friend of the Coldstream Guards' military chaplain. He was allowed inside without showing identification, where he reportedly spent the evening eating and drinking with senior officers. "Within a couple of hours, he was drinking with the officers in the bar and telling them stories of how he had served in Iraq," a source told TalkTV. "He was telling lots of tall stories and the lads were enjoying his banter and having a few drinks. It was only later when he started talking about how he had worked as an ejector-seat test pilot and had some organs replaced that the chaps started to get suspicious."

The man was removed and "no further action was required," they said. Queen Elizabeth returned from her visit to Sandringham just hours later. A source notes that there was no breach of security at Windsor Castle and there was no breach of royal security. A spokesperson for the British Army tells PEOPLE: "The Army takes this breach of security extremely seriously and it will be thoroughly investigated as a matter of priority. This incident is now part of an ongoing investigation and it would therefore be inappropriate to comment further at this time." This isn't the first time an unwelcome guest made their way onto royal residence grounds. In 2021, an intruder with a crossbow was arrested on the grounds of Windsor Castle as Queen Elizabeth and members of the royal family, including Prince Charles and Camilla, Duchess of Cornwall, celebrated Christmas at the castle. "We can confirm security processes were triggered within moments of the man entering the grounds and he did not enter any buildings," Thames Valley Police Superintendent Rebecca Mears said in a statement.

In a 2012 interview with The Independent on Sunday, Fagan recalled being in the monarch's bedroom. "I was scareder than I'd ever been in my life," he said. "Then she speaks and it's like the finest glass you can imagine breaking: 'Wawrt are you doing here?!' " While it was reported that the two had a long conversation, Fagan said: "Nah! She went past me and ran out of the room; her little bare feet running across the floor."
