When a trainee chef Essayas Kassahun was stabbed to death in Clerkenwell almost eight years ago, a teenager was found guilty of his murder, and sent to prison.
But tonight, having spent more than a quarter of his life behind bars, Sam Hallam is a free man.
He'd always protested his innocence. In fact, he claims he wasn't even in the area at the time of the killing.
His lawyers told the Court of Appeal today there had been a "serious miscarriage of justice."
The prosecution said they wouldn't fight the case, and the judge released him on bail.
Lady Justice Hallett said the court would give its ruling in the case tomorrow.
