British police are on high alert after five attacks blamed on terrorism this year. In August a man wielding a sword outside the palace was charged under terrorism laws. Three police officers suffered minor injuries detaining him.
There have been a number of other incidents in recent years in which people have tried to get into the palace grounds. Last October, a 21-year-old man was arrested after scaling a gate of the palace. He was later detained under a hospital order.
In May 2016, a man with a conviction for murder climbed over the wall and walked for about 10 minutes around the grounds of the palace before being arrested. He was jailed for four months.
Four years ago, a man armed with a knife tried to enter through a gate and was later jailed for 16 months. A month earlier, two men were arrested following a break-in at the palace.
One of the biggest security breaches at Buckingham Palace happened in 1982 when an intruder, Michael Fagan, climbed a wall and wandered into a room where the queen was in bed.
