 Billionaire Donald Trump has said he "may sue" a Twitter user who tricked him into retweeting an image of British serial killers Fred and Rose West. 
 
 Mr Trump shared the spoof message that claimed the pair looked at him as a "big inspiration" and asked him to "RT for their memory". 
 
 Later he tweeted: "I guess this teaches you not to be nice or trusting." 
 
 Fred West was charged with a dozen murders in Gloucester but killed himself before the trial in 1995. 
 
 Rose West was convicted of 10 murders - many at the couple's home in Gloucester - and jailed for life. She was told when she was sentenced in 1995 that she should never be released. 
 
 Mr Trump was contacted by the Twitter user early on Monday, urging him to retweet the image of the Wests. 
 
 The tycoon, who features on the US version of reality TV show The Apprentice, later deleted the message after it was widely shared on the social media site.

 Addressing the incident, Mr Trump later tweeted: "Some jerk fraudulently tweeted that his parents said I was a big inspiration to them + pls RT-out of kindness I retweeted. Maybe I'll sue. 
 
 "I thought I was being nice to somebody re their parents. I guess this teaches you not to be nice or trusting. Sad!" 
 
 Mr Trump has yet to respond to requests for a comment from the BBC. ||||| But his latest mistake is perhaps his most laughable to date – in the very poorest of tastes. 
 
 The business magnate accidentally retweeted a message from a follower asking Trump to share an image purportedly of his recently deceased parents in loving tribute to their memory. 
 
 “My parents who passed away always said you were big inspiration,” the post from @Feckhead read. 
 
 “Can you pls RT for their memory?” 
 
 Unbeknownst to Trump, however, @Feckhead is “failed comedian” Phil Bradbury, and the image he posted was actually one of convicted serial killers Fred and Rosemary West. 
 
 The response from followers was thus: 
 
 @realDonaldTrump @feckhead They seem like lovely, kind caring parents, don't you think Donald? Dom Joly (@domjoly) September 29, 2014

 The notorious married murderers were found guilty of torturing and raping scores of young girls, and killing 11 of them, between the years 1973 and 1979. Their victims included Fred’s stepdaughter, who Rosemary murdered while Fred was in prison for theft. 
 
 The pair were finally charged in 1994. Fred took his own life before the case when to trial. Rosemary was found guilty of 10 counts of murder in November 1995 and is currently serving a life sentence. 
 
 The scene of many of their most heinous acts, their Gloucester residence 25 Cromwell Street, was demolished in 1996 and converted into a landscaped footpath. 
 
 Last month, Trump caused mild outrage by deliberately tweeting the following about ebola doctors.

– "I guess this teaches you not to be nice or trusting," Donald Trump complained yesterday after he was fooled into retweeting a picture of notorious British serial killers Fred and Rosemary West. The tycoon says he may sue the "jerk" who told him his "parents who passed away always said you were big inspiration" and asked him to retweet the photo in their memory, reports the BBC. Trump quickly deleted the picture of the Wests—who murdered at least 11 young women in the 1970s—but not before the mistake had been widely shared, reports the Independent, which rounds up some of its favorite responses, including a picture of Freddy Krueger with the caption "Please retweet for my brother who has a disfiguring skin condition." (Also getting Trump's goat: Critics who say putting his name in 20-foot-tall illuminated letters on a Chicago skyscraper is a little tacky.)
