Gardaí and Dublin Bus are investigating after a bus was filmed being driven on a footpath and cycle lane between Rathfarnham and Terenure in Dublin earlier this week.

Footage of the incident was posted on social media.

A spokesperson for Dublin Bus said that it was "under investigation and will be investigated fully".

A statement from An Garda Síochána said that "it commenced inquiries into an alleged incident of dangerous driving".

The incident was raised at a meeting of the Dublin City Traffic and Transport Committee last night during a debate on a motion on the Road Safety Authority's 'Be Safe, Be Seen Campaign'.

Speaking during the meeting, Fianna Fáil Councillor Keith Connolly said the incident was an issue for gardaí.

Speaking to RTÉ News this morning, Mr Connolly said he believed the incident was "very serious and very worrying".

The Minister with responsibility for International Road Transport and Logistics said she had seen the video.

Hildegarde Naughton said it was "very concerning" and that a garda investigation is under way.

She said it was "extremely serious" and should not have happened.

Ms Naughton said Dublin Bus will share official footage of the incident with the gardaí.

Ms Naughton, who oversees the "Safe Routes to School Programme" said that footpaths and cycleways "are the exact pieces of infrastructure... that we need to ensure are safe."

"So when we see a public transport bus like this mounting a footpath and cycleway it is extremely concerning, and is absolutely unacceptable," Ms Naughton said.

'Terrified'

In the footage the bus can be seen driving past the entrance to Joyce Porto's home on Rathfarnham Road.

Ms Porto told RTÉ News that she was "terrified" when she saw the video circulating on social media.

"I have two small kids... they are five and seven and normally when we leave the house early in the morning, they run (to the path in front of the house)," she said.

Ms Porto said that she warns her children to be very careful and aware of the busy road in front of their house, but hoped the footpath at least would be "a safe place to walk."
