A number of passengers were taken to hospital after the incident.
Gardaí are investigating a bus crash in Offaly which saw multiple people taken to hospital.
The single-vehicle collision occurred on the R444 at Tullaghbeg, just outside Clonmacnoise, yesterday morning at around 10.30am.
A number of passengers were conveyed to Portiuncula University Hospital, but Gardaí say this was just as a "precaution."
They're asking witnesses, particularly those with camera or dashcam footage, to come forward.
Anyone with information is being asked to contact Tullamore Garda Station.
