In the aftermath of the fatal school shooting in Germany - where 17-year-old Tim Kretschmer murdered 15 people before turning the gun on himself - police said Kretschmer had posted a warning of his attack on the internet.
Less than 24 hours after the attack, Wurttemberg's Interior Minister - Heribert Rech - had read out a message thought to have been posted by Kretschmer.
"I have weapons here, and I will go to my former school tomorrow and then I will really do a grilling… you will hear of me tomorrow. Remember the place's name: Winnenden."
But it is now looking probable that the internet posting was a hoax.
