Dublin Fire Brigade is investigating an incident in which a child became trapped in an ambulance while being taken to hospital.

No one was injured in the incident, which happened in the city on St Patrick's Day.

The ambulance was on its way to Temple Street Children's Hospital, when its power failed causing all the doors to lock.

A fire engine was dispatched to rescue the child, the child's parent and the paramedic who were trapped inside.

It is understood the rescue efforts were hampered by the fact that the ambulance's emergency exit did not work, and it took 40 minutes to free the occupants.

The child was safely transferred to hospital and successfully treated, before returning home shortly afterwards.

Dublin Fire Brigade said it is taking the incident very seriously, and stressed that it was an isolated event, which will be thoroughly investigated.
