Detectives investigating the murder of a Scottish banker shot dead on his doorstep 12 years ago are considering new information about the case.

Allegations regarding the alleged killer of Alistair Wilson and their motive were passed to Police Scotland by the BBC following a phonecall from a member of the public.

Mr Wilson was killed at his home in Nairn on November 28, 2004, and the 30-year-old's murderer has never been caught.

On Monday, Police Scotland said it remains "absolutely committed" to solving the case.

Senior investigating officer detective superintendent Gary Cunningham said: "The inquiry into the murder of Alistair Wilson remains active and ongoing.

"We will continue to consider all forensic and investigative opportunities as well as appeal to anyone who has any information about Alistair's death which could help this inquiry to come forward.

"We remain absolutely committed to tracing the person responsible and remain in regular contact with Alistair's family and updates as the investigation continues."

Anyone with any information about the case has been asked to contact Police Scotland on 101 or Crimestoppers on 0800 555 111.
