A man has been taken to hospital and arrested after he allegedly handcuffed himself to Buckingham Palace.
Police were called to the Palace on Thursday evening over reports a man had attached himself to the gates, with a number of self-inflicted injuries.
The force said the man had been threatening to hurt himself. Thankfully, it's understood nobody was seriously injured in the brief incident.
Officers said he attached himself to the palace entrance shortly before 5.30, with the small stand-off wrapped up an hour later.
The Metropolitan Police originally tweeted just after 6pm: "At around 17:23hrs a man approached the gates of #BuckinghamPalace & handcuffed himself to them.
"Officers in the area immediately approached the man, believed aged in his 30s, who began threatening to harm himself.
"LAS are also on scene. Police are trying to speak to the man & bring the situation to a swift conclusion to ensure his safety and welfare."
An update three hours later said: "UPDATE – 2100hrs - Cordons remain in place & situation still ongoing.
"Officers are still speaking to the man, who has sustained a number of self-inflicted slash injuries. Police are working to bring the situation to a safe end as quickly as possible."
