A man has been arrested outside Buckingham Palace after throwing suspected shotgun cartridges into Palace grounds, police said in a statement. The man was arrested on suspicion of possession of an offensive weapon. There are no reports of any injuries and the incident is not currently being treated as terror-related.

Security Minister Tom Tugendhat, described the response as “a fantastic piece of policing,” adding that “a huge security operation” has been put in place ahead of the Coronation.
“As you saw last night, the police and security services are absolutely ready to intervene when necessary,” Minister Tugendhat said.
The King and the Queen Consort, who live at nearby Clarence House, were not at Buckingham Palace at the time the arrest happened, although the King did host Australian Prime Minister Anthony Albanese at the palace earlier that day.
