A mother who was injured when a tree fell on her and her son at a Pembrokeshire holiday attraction has left hospital.

Twenty-eight-year-old Emma Davies Hughes, a PE teacher from Cross Hands, Llanelli, and her three-year-old little boy were seriously injured in the incident at Manor House Wildlife Park, St. Florence, last Tuesday.

Both were airlifted to Morriston Hospital, Swansea, after being freed from beneath the tree by firefighters.

The little boy, who suffered serious head injuries, was later transferred to the intensive care unit at the University Hospital of Wales, Cardiff.

Pembrokeshire County Council's public protection division are carrying out an investigation into the incident.

Said a spokeswoman: "A full survey of the tree has been carried out by a tree specialist. It will take some time before a detailed report is available.

"We have a full list of witnesses to the incident, which was gathered by the police on site. We will talk to them as and when it is appropriate.

"It is too early to say how long the investigation will take."

The park is owned by TV celebrity Anna Ryder Richardson and her husband Colin MacDougall who released a statement saying they were 'devastated' by the incident.
