AN Iraq war veteran jailed for the racist murder of a Bangladeshi waiter almost 18 years ago has lost a bid to have his conviction overturned.

Shamsuddin Mahmood, 26, was shot by a masked gunman in front of diners while working in an Orkney restaurant in 1994.

Former soldier Michael Ross, 33, was jailed for life and ordered to spend at least 25 years behind bars after being convicted of the killing at the High Court in Glasgow in 2008.

Ross, who was just 15 at the time of the murder, had his appeal against the conviction heard at the Court of Criminal Appeal in Edinburgh earlier this year.

His legal team argued that police interviews, carried out without a lawyer present when Ross was 15 and 16, were "unfair". It was claimed the Crown's actions, in relying upon the contents of the interviews, were incompatible with his human rights.

However, Scotland's top judge, the Lord Justice General Lord Hamilton, who heard the case with Lords Carloway and Bonomy, upheld the conviction yesterday.

The case against Ross, a former Black Watch soldier decorated for outstanding service in Iraq in 2005, was brought to court after police carried out a cold-case review in 2007. The jury found him guilty of murder by majority verdict.

He was later given a further five-year sentence for trying to flee court after the verdict and stashing weapons in a car.

Ross's legal team may seek leave to take the appeal to the UK Supreme Court after they have considered the judgment in full.
