Pembrokeshire emergency services are involved in a major search for an 11-year-old boy who is thought to have fallen into the River Towy on Tuesday afternoon.

Tenby coastguards are involved in the search near Glangwili Hospital, which is being co-ordinated by police, as well as the senior control operations officer.

Dyfed-Powys Police said the alarm was raised just before 4pm on Tuesday.

Police, firefighters, coastguards, lifeboats and an RAF Sea King rescue helicopter were all involved in the search in Tanerdy, yesterday.

The search was called off overnight but has resumed this morning.

At 10.30am on Wednesday morning Inspector Eric Evans spoke to the media.

He said a specially trained officer is working with the family in order to provide support and maintain communication between the services and the community at this very difficult time.

"The search continues in hope", he said.

Asked if police were confident that the boy had actually fallen into the river, Insp Evans said: "We are not 100 per cent sure that the boy has gone into the water although we are fairly confident that he has. "We are conducting a thorough search of the area and following every lead in order to find him.

"As a police service we deal with missing person reports on a daily basis so are very experienced and well-trained and will be systematic in our approach to finding him."

Insp Evans said there were around 50 personnel from all services systematically searching the river.

"We are being guided by coastguard in relation to the flow of river and tidal water as to how far the boy could have travelled", he added.

Asked if the boy was with other children at the time of the incident, Insp Evans said: "Our focus at this time is to search and find the boy. When we have done that we will then look at circumstances around the incident."
