The body of four-year-old Dylan Cecil who slipped from a jetty in North Somerset is believed to have been washed out to sea after specialist sonar equipment failed to find him.
Dylan, who was from Kettering was on holiday with his family when he stumbled into the muddy water at Burnham-on-Sea at 6pm on Sunday.
Volunteers from the UK underwater rescue organisation SARbot used specialist sonar equipment to scour the water for Dylan's body today. But after spending hours on the water it could not be found.
Dylan's family remained at the scene today and were being updated about the recovery operation.
