Police cannot not be 'sure' missing boy, 11, is in river
Police have said they are not "100% sure" a missing 11-year-old boy is in a river where they have been searching.
It was feared the schoolboy fell into the River Towy on Tuesday at about 16:00 GMT.
Firefighters, the coastguard, a lifeboat crew and an RAF Sea King rescue helicopter joined the search.
But Insp Eric Evans from Dyfed-Powys Police told a news conference on Wednesday there was always an "element of doubt" when dealing with children.
