A POLICE officer serving a four-year jail sentence has officially resigned, it was revealed yesterday.

Edmund Ross, 47, an officer with Inverness-based Northern Constabulary for more than 20 years was jailed at the High Court in Inverness last year.

The court had been told that his teenage son was a murder suspect for the shooting of waiter Shamsuddin Mahmood, 26 at the Mumutaz restaurant in Kirkwall, Orkney in 1994. The court heard firearms expert Ross hid bullets at his house from detectives after he discovered that the one used in the killing was the same calibre and bore similar markings to his.

His son, Michael, 19, remains a suspect.
