The trio arrested after a bomb scare at Glasgow's Buchanan Bus Station have been released.

Police raced to a report of a 'potentially suspicious item' at the city centre travel hub shortly after 1pm on Wednesday, November 20.

After the alarm was raised, emergency crews, including the bomb squad, medics, cops, and firefighters rushed to the scene. 

Shortly after 9.30pm last night, police revealed a 'controlled explosion was carried out' at the bus station, however, nothing suspicious was found.

However, cops have now said the men have been released without charge.

Superintendent Derrick Johnston said: "The initial report was treated as a credible threat and, as a precautionary measure and in accordance with procedures, the surrounding area was closed to the public and a cordon put in place.

"The Royal Navy Explosive Ordnance Disposal team (EOD) carried out a controlled explosion after an assessment was made of the impact to nearby gas mains and local train lines.

"The item was then examined and confirmed to be innocent in nature, posing no risk to the public.

"All areas reopened by 9.45pm and I thank the public for their patience and understanding."
