Business tycoon Donald Trump was left red-faced after an internet prankster tricked him into tweeting a picture of serial killers Fred and Rose West.
Philip Bradbury sent the billionaire a picture with the message: 'My parents who passed away always said you were big inspiration. Can you pls RT for their memory?'
The media team who run the 68-year-old multi-millionaire's official Twitter feed via @realDonaldTrump immediately retweeted the message to his 2.7million followers.
Twitter users took to social media to congratulate the prankster, Philip Bradbury.
TV funnyman Dom Joly tweeted to Trump: 'They seem like lovely, kind caring parents, don't they Donald?'
William Ellis ?@wellis321 tweeted 'Just a lovely insight into the mind of a dim witted money podgerer. Thank you and good work indeed.'
Philip pulled his prank at about 12.20pm on Monday and within an hour it had been retweeted 2,500 times.
Evil Fred West tortured and raped numerous young women and girls - murdering at least 11 of them - including members of his own family.
The crimes often occurred in the couple's homes in Gloucester, England, at 25 Midland Road and later 25 Cromwell Street, with many bodies buried at or near these homes.
Fred killed at least two people before collaborating with Rose, while Rose murdered Fred's stepdaughter when he was in prison for theft.
The majority of the murders occurred between May 1973 and August 1979 at 25 Cromwell Street, which became known as the House of Horrors.
The pair were finally caught and charged in 1994. Fred West committed suicide before going to trial, while Rose West was jailed for life the following year after having been found guilty on 10 counts of murder.
Their house at Cromwell Street was demolished in 1996 and the space converted into a landscaped footpath, connecting Cromwell Street to St. Michael's Square.
Trump's embarrassed PR team finally deleted the retweet an hour after posting it in a bid attempt to hide the gaffe.
But by then it had already been retweeted more then 4,800 times.
Other Twitter mischief-makers then flooded Trump with requests for retweets - as you can see below.
