Michael Ross in Shamsuddin Mahmood murder conviction review bid

Michael Ross was found guilty of the murder of Shamsuddin Mahmood

A man jailed for the murder of a waiter on Orkney has asked the Scottish Criminal Cases Review Commission to examine his conviction.

Former Black Watch sniper Michael Ross was 15 when Shamsuddin Mahmood, 26, was shot in the head in Kirkwall's Mumataz Restaurant in June 1994.

Ross was sentenced to a minimum of 25 years after being found guilty in 2008.

The SCCRC said it had received an application but had not yet considered whether the case would be reviewed.

A decision is expected to be made over the next three months.

Ross' bid to have his murder conviction overturned was rejected by the Court of Criminal Appeal in Edinburgh earlier this year.

Ross, of Inverness, was then refused permission to take his appeal against his conviction to the Supreme Court.

Mr Mahmood, born in Bangladesh, was shot in full view of a room full of diners, including families with children, by a masked gunman.
