A woman was arrested near Buckingham Palace on Friday morning after she ran toward the royal grounds clutching three large knives – two days after a man climbed the front gates while Queen Elizabeth was in residence.

The screaming woman, who was wearing a pink T-shirt, shorts and a military-style camouflage hat, ran toward St. James’s Park, where she apparently threw the blades into the gardens of Wellington Barracks, the Telegraph reported.

Mounted police were seen galloping along Birdcage Walk in pursuit of the unhinged woman, who began to laugh hysterically while being handcuffed along the route famed for the Changing of the Guard, according to the news outlet.

“Three knives have been recovered. She remains in custody. Enquiries continue,” a spokesman for the Metropolitan Police said.

The woman, whose name was not released, was arrested on suspicion of possession of points and blades, and racially aggravated public order, the official said.

The racial offense was a result of comments the suspect made after she was arrested.

A private security guard who worked nearby said the woman was screaming during her rush toward the palace.

Asked if he heard what she said after being caught, the man said: “That’s the scary thing, she was just laughing.”

On Wednesday, a 22-year-old man was arrested after he climbed the front gates of Buckingham Palace, according to the Guardian newspaper.

Police said he wasn’t carrying any weapons and that the incident was not believed to be terrorism-related, the news outlet reported.

He was arrested by officers from the Metropolitan Police’s Royalty and Specialist Protection Command.

In a previous security breach at the palace, a homeless man was found sleeping on the grounds last year, the BBC reported.

In September 2013, a security review was launched after an intruder managed to scale a fence and get inside the palace before being caught.
