A man who was convicted of murder in 2005 has had his conviction quashed after prosecutors announced they would not oppose his appeal.

Yesterday, 24 year-old Sam Hallam, was released on bail after prosecutors made their decision at the Court of Appeal. Today, the appeal judges ruled that his conviction should be quashed. Earlier, the court heard from his QC that Hallam was the victim of a "serious miscarriage of justice" because the Metropolitan Police had failed to investigate his alibi and problems with the prosecution witnesses.

After the conviction was quashed, he said: "I don't want anyone else ever to suffer what I've been through."

Hallam was 18 when he was sentenced to life in prison for the murder of trainee chef Essayas Kassahun, 21, who died after being attacked by a group of youths on the St Luke's estate in Clerkenwell in October 2004. His family said he had been left in shock following the prosecution's decision yesterday.
