The artist behind the solid gold toilet which was stolen from Winston Churchill's former home on Saturday, has asked the thieves to let him know "how it feels to pee on gold" Sky News has reported.

A gang of thieves stole the  18-carat gold toilet from Britain's Blenheim Palace, causing flooding that damaged the world-famous stately home.

The fully-functioning toilet, dubbed "America", was created by Italian artist Maurizio Cattelan and estimated to be worth around £4.8m million.

 "When this morning I was informed about the robbery I thought it was a prank and it took me a while, after a few checks, to come to the conclusion that it was true and it wasn't a surreal movie where instead of the jewels of the crown, the thieves went away with a b***** toilet," Cattelan said.

"I always liked heist movies and finally I'm in one of them.  "Dear thieves, please, if you are reading this, let me know how much you like the piece and how it feels to pee on gold."

A 66-year-old man was arrested following the burglary, which took place before dawn at the 18th-century estate near Oxford, southern England.

The toilet was one of the star attractions in an exhibition of Cattelan's works that opened on Thursday at the palace, a UNESCO World Heritage Site.

Visitors were able to book time slots to use it -- but only for three minutes each, to limit the queues.

More than 100,000 people used the loo during the year it was on display at New York's Guggenheim Museum.

"The offenders broke into the palace overnight and left the scene at about 4.50am. No-one was injured during the burglary," police said in a statement.

Detective Inspector Jess Milne of Thames Valley Police said she believed "a group of offenders used at least two vehicles" -- and left a mess behind them.

"The piece of art that has been stolen is a high-value toilet made out of gold that was on display at the palace," she said.

"Due to the toilet being plumbed into the building, this has caused significant damage and flooding."

Blenheim Palace said it was "saddened by this extraordinary event, but also relieved no-one was hurt".

- No guards -

The palace is home to the 12th duke of Marlborough and his family, and was also the birthplace of British wartime leader Winston Churchill.

The duke's brother, Edward Spencer-Churchill, who founded the Blenheim Art Foundation, said last month he was relaxed about security around the gold toilet.

"It's not going to be the easiest thing to nick," he told The Times newspaper.

"Firstly, it's plumbed in and secondly, a potential thief will have no idea who last used the toilet or what they ate. So no, I don't plan to be guarding it."

He added: "Despite being born with a silver spoon in my mouth I have never had a shit on a golden toilet, so I look forward to it."

Cattelan, who is known for his provocative art, has previously described the golden toilet as "one-percent art for the 99 percent".

The Guggenheim had offered the loo on loan to US President Donald Trump, but he declined.

The Italian artist's exhibition at Blenheim runs until October 27 and includes a taxidermied horse hoisted onto the ceiling of an ornate reception room.

Blenheim has previously hosted exhibitions of work by Ai WeiWei, Yves Klein, Jenny Holzer, Michelangelo Pistoletto and Lawrence Weiner.

Police said they were looking at CCTV footage to help them in the search for the gold toilet, adding that nothing else was believed to have been stolen.
