Dublin Fire Brigade is investigating what caused a child to become trapped in an ambulance on St. Patrick's Day. The ambulance was taking the child to Temple Street Hospital when its power failed and all of its doors were locked.

It is understood a paramedic was forced to kick a window out to escape.

The Fire Brigade says it is taking the incident 'very seriously' and has launched a 'thorough' investigation. It happened when an ambulance from Kilbarrack Fire Station was dispatched to a child who was suffering anaphylactic shock.

While the child was being transferred to hospital the power failed and all on-board were trapped.

A fire engine was sent to try to free the child, parent and the crew. But in the end, a paramedic on-board had to kick out a window to escape.

The patient was later treated at Temple Street before returning home.

Dublin Fire Brigade says it wants to ensure that similar events do not happen again. It is asking the manufacturer what could have caused the failure.
