The reward for information about fugitive Derek Ferguson has been increased by £5000, as police have issued a renewed appeal. 

Glasgow-born Ferguson is wanted in connection with the murder of Thomas Cameron, who was shot outside a pub on Auchinairn Road, Bishopbriggs, 15 years ago on June 28, 2007.

An international warrant remains in place for Ferguson's arrest. He remains on the National Crime Agency's "Most Wanted" list.

Last year, on the 14th anniversary of Mr Cameron's murder, a £5000 reward was issued by Crimestoppers.

One year on, the reward has been increased to £10,000. 

Meanwhile, Police Scotland is renewing its appeal to anyone who has knowledge about the current whereabouts of Ferguson to get in touch with any information that could help track him down.

A dedicated website giving members of the public access to a form to send information directly to the Enquiry Team has been set–up.

Anyone submitting information can select to remain anonymous. To go to the website, click here.

Officers leading the investigation believe the fugitive may be in Spain but say it's unlikely he will be known by his original name or be speaking with a Scottish accent.

Detective chief superintendent Paul Livingstone said: “Despite 15 years having passed, Police Scotland’s investigation into the murder of Thomas Cameron continues.
