A mysterious loud noise that left transport police at Glasgow Central station baffled for hours was a burst bike tyre, it has emerged.

The noise, which a member of the public described as a"loud bang", was heard by commuters in the concourse area of the station at about 12.20pm on Friday.

British Transport Police based in the station then reportedly ran to investigate.

Officers were at first unable to locate the source of the noise after initial enquiries, including a review of CCTV footage around the time of the incident.

However, they finally determined the cause of the sound was a bicycle tyre bursting, shortly before 4pm.

Posting on Twitter, the Scottish division of the British Transport Police said: "Mysterious noise update... loud noise was in fact a burst bike tyre."
