One of the two children injured in a fall from a second-storey apartment balcony on Friday in Waterford city has been released from hospital.

Sister and brother Nevaeh (7) and Jayden (3) O’Neill fell from the balcony at Mount Suir apartments in Gracedieu at 10.40am.

A number of ambulances, fire units, gardaí and Waterford City and County Council officials have been attending the incident at Block C, Mount Suir apartments, in Waterford city.

The siblings fell more than 20ft when a pane of glass on the balcony railing crashed to the ground. They had been playing with two other siblings who were not injured.

The two children were taken by ambulance to University Hospital Waterford (UHW). Nevaeh was discharged from hospital on Friday night and returned home to her parents Ryan O’Neill and Regina Smith.

Jayden, who was transferred to Temple Street Hospital in Dublin as a precautionary measure due to head injuries, remains under medical care. He narrowly missed falling on a large shard of glass.

The council has owned Block C of the Mount Suir apartment complex for the past six years.

Garda forensic teams have examined the balcony.

In a statement Waterford City and County Council said it has been notified of a serious incident at the Mount Suir Apartment complex in Waterford City on Friday, March 20th.

The council confirmed it has opened an investigation.

“The council has reached out to the family to offer support and a formal investigation into the incident has commenced,” the statement added.

Mayor of Waterford City and Council Séamus Ryan said his thoughts and prayers are with the family involved and the children.

“The council are fully investigating what happened and a structural engineer is on site currently. We will get to the bottom of what happened,” the Labour councillor said.

The council held an emergency meeting on Friday afternoon with Tramore-Waterford City West’s six elected councillors at 3.30pm.

Those living in Block C have been informed by council officials to stay off their balconies until an inspection is carried out by the council next Monday.

Last year the council received 25 complaints from its tenants, the majority of which focused on chronic leaking issues.
