At first glance, it was all too credible: a 24-year-old Syrian had been queuing for days in the cold at Berlin's notoriously chaotic refugee registration centre Lageso even though he was ill.
Homeless and penniless, he finally went into cardiac arrest on the way to hospital and died, according to the account posted on Wednesday by kind-hearted volunteer Dirk Voltz, who had taken the man in.
"I acted out of a relationship based on trust," said a dismayed Diana Henniges, from the aid group, who had confirmed the purported death to national media before Voltz finally admitted he had invented it.
In a gripping "live" text-message style exchange with a friend published online, Voltz said he rang for an ambulance as the man was suffering from a "39.4 degree fever, chills and could no longer speak".

He told his friend to find an Arabic speaker quickly to communicate with the refugee, but after his friend gave him a number, he said it was too late and the Syrian had died.
But as national media began reporting on the "tragedy", emergency services said there was no trace of such a case.
Finally, Voltz confessed to police he had, in a drunken stupor, lied.
"It is indicative of this overly excited, sometimes hysterical time, but also of the state of Lageso, that so many people have immediately believed such a death," Berlin daily Der Tagesspiegel said in an editorial.
