Flamboyant tycoon Donald Trump has inadvertently tweeted an image of serial killers Fred and Rose West following a Twitter prank.
A Twitter user sent a message to the billionaire saying: “My parents who passed away said you were a big inspiration. Can you please retweet (the message and image) for their memory?”
The user attached the photo of the notorious killers, which Mr Trump retweeted to more than two million followers.
Within minutes the post had been mentioned hundreds of times, with some horrified users pointing out that he had been trolled.
One user, Tom Eldridge, said: “Social media 101 lessons for Donald Trump. I would do some research before posting.”
Mr Trump later deleted the post.
On Monday, the real estate mogul threatened to sue the “jerk” who tricked him into sharing the image.
“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,” he wrote.
“I thought I was being nice to somebody re their parents. I guess this teaches you not to be nice or trusting. Sad!”
Fred West killed at least 12 women and girls between 1967 and 1987, including family members.
His wife Rose took part in the majority of the killings.
Fred killed himself while awaiting trial in 1995, while Rose is currently serving a life sentence.
