Buckingham Palace was put under lockdown Tuesday after a man was caught carrying and throwing suspicious items onto the royal grounds — just four days ahead of King Charles’ Coronation.

The UK’s Metropolitan Police arrested the man after he approached the gate around 7 p.m. local time and “threw a number of items” suspected to be shotgun cartridges.

The cops confiscated a “suspicious bag” from the man and conducted a controlled explosion as a precaution.

“Officers worked immediately to detain the man and he has been taken into police custody,” Chief Superintendent Joseph McDonald said in a statement.

“There have been no reports of any shots fired, or any injuries to officers or members of the public.”
The DailyMail reported that no members of the royal family were inside the palace at the time of the incident.
