Dublin Bus has described reports this morning on the cause of the Wellington Quay crash as "pure speculation".
The company's spokeswoman, Ms Grainne Macken, refused to comment on the claims the driver at the centre of the investigation accidentally got his foot stuck on the accelerator
She said the company would say tomorrow when its investigating team's findings would be published. Ms Macken described media reports published prior to the publication of the Dublin Bus inquiry as "speculation or hearsay."
The Starnewspaper reported this morning that it had gained access to the Garda investigation of the crash, which killed five people.
Dublin Bus and the Garda have begun investigations into the incident, but the newspaper claims detectives are satisfied they know what happened.
The report said officers had established that the engine of the out-of-service bus was running, with its automatic transmission in drive gear, when the first driver handed the vehicle over to another colleague who was starting a new shift.
The newspaper claims investigators believe the second driver then lost control of the vehicle after he sat into the cab moments later and released the handbrake.
