Gardaí said eight people were taken to hospital. Among those hospitalised was a three-month-old baby who was taken to Temple Street Hospital for observation. She has since been discharged from hospital.

The Mater Hospital said five patients were being treated there.

Luas red line services between Blackhorse and The Point and Connolly were suspended for a time after the incident.

In a statement this afternoon, Transdev said: "Our priority is our staff and passengers' well-being at the time," added the statement."
