Deputy First Minister Huw Irranca-Davies, described the incident as a “real tragedy” and said: “Our thoughts go out to the family and those in the local area as well.

“That’s the immediate concern, to make sure we have that support there in place for the family and then to understand what has gone wrong, but right now our hearts go out to all those affected.”

Residents of the village said they saw police cars and ambulances on the street late Sunday evening, with the “quiet community” finding it difficult to come to terms with the “horrendous” events of Sunday night.

Rogiet county councillor Peter Strong described the village as being in mourning, but vowed residents would “stand together”.

“It’s a deep and profound sense of shock that such a thing should happen in amidst our quiet community.”

Mr Strong appealed to local people to “stay calm [and] to give the family the space they need to grieve in peace”.
