Three people were taken to hospital yesterday after a double-decker bus veered out of control and hit a garden wall when the driver apparently collapsed at the wheel.
A young passenger tried to take control of the vehicle, said witnesses, but could not stop the bus from crashing into the wall of a house in Crumlin, Dublin.
The driver of the 121 route bus and both passengers on board at the time were taken to hospital where they were treated for minor injuries.
Dublin Bus and the Garda have launched separate investigations into the incident which occurred at the junction of Clonard Road and Kildare Road at about 9.15am.
A witness said that the young man "was trying to take control of the bus. He was trying his best but he couldn't. I don't think the driver knew where she was.
"By that time it had hit the front wall and was partly in the front garden.
"There was an old lady on the bus and she was screaming because the bus was swerving all over the place."
The eyewitness also said that panic descended upon the scene after the bus hit the wall.
"It was just panic. Everybody started running. Everybody tried to help. The driver was actually in the cab, but nobody could get her out.
"A man got a screwdriver and was able to open the driver's cab and get out the driver."
The bus was en route from Drimnagh to Cabra.
