A Facebook user has posted a video of Translink bus ablaze on Thursday evening near the Antrim Road area of north Belfast.
Matt Donnelly posted the video with the comment: "Nothing to see here - just a bus on fire."
He managed to capture the footage above as it began to catch fire.
Another user, who saw the vehicle later in the evening, said the bus was "proper burnt out, the Translink guy was at the back with a clipboard."
Translink said on Twitter that they are aware of the incident and it was being attended to.
Translink could not be reached for further comment. There is no further information at this time.
