Dublin Bus is investigating after footage on social media appeared to show a passenger hanging on to the back of a fast-moving bus.

It is believed to have been recorded as the bus was driving through Finglas this week.

A spokesperson for Dublin Bus has confirmed it is now looking into the incident.

In a statement, the company warned that the action shown in the footage is unsafe and extremely dangerous.

The company said it strongly discourages anyone from partaking in such reckless behaviour that could result in serious injury.
