The search for a man missing since December 29 has been stepped up.

Police have been stopping motorists in the area where 49-year-old Scott McSporran was last seen in Dumbarton.

Officers interviewed 13 people on Napier Crescent and surrounding streets in Brucehill on Friday evening.

Mr McSporran, from Clydebank, was last seen nearby at around 8pm on December 29.

Sergeant Calum Fulton said: "I would like to thank everyone we spoke to for their co-operation. We are currently assessing the information provided by those we spoke to last night and we will follow up any relevant lines of inquiry.

"Scott's family are extremely upset by his disappearance and just want to know he is safe and well."
