'I Am Here To Kill The Queen': Queen Intruder To Police

A man arrested at Queen Elizabeth's Windsor Castle home on Christmas Day last year wearing a mask and holding a crossbow told security "I am here to kill the queen," a British court heard on Wednesday.

Jaswant Singh Chail, who has been charged under Britain's Treason Act, had spent months planning the attack and trying to gain access to the royal family.

Prosecutors said Chail, from Southampton, recorded a video before he entered the grounds of the castle where the 96-year-old monarch mostly resides.

She was there on the day of the intrusion.

"I am sorry for what I have done and what I will do.

"I am going to attempt to assassinate Elizabeth, queen of the royal family.

"This is revenge for those who died in the 1919 massacre," Chail said, referring to an incident when British troops shot dead nearly 400 Sikhs in the city of Amritsar in northwestern India.

"It is also revenge for those who have been killed, humiliated and discriminated on because of their race," he added.

The prosecution said Chail had entered the grounds at 8:10 a.m. local time and was spotted by a protection officer in an area where the intruder would have access to the private quarters of the castle.

The officer asked how he can be helped and Chail responded; "I am here to kill the queen."

The officer drew his taser and shouted at Chail to get on his knees and drop the crossbow. Chail complied.

Chail has been charged with making threats to kill, possession of an offensive weapon and an offense under section 2 of the Treason Act 1842, which details punishment for having a weapon with intent "to injure or alarm Her Majesty."

The case will be heard next at London's Old Bailey on a date yet to be confirmed.
