Diver rescued after 2 days lost at sea said his 14-year-old son was 'too weak and could not survive,' say reports

• Adrian Peter Chesters and Alexia Alexandra Molina were found on April 8, after being lost at sea for two days.
• Chesters said his son, 14, had died at sea as he was "too weak" to survive.

A British man and French woman have been rescued after being lost at sea for two days off the coast of Malaysia, but the man has told authorities his teenage son had died.

Writing an announcement on Facebook, the Malaysian coast guard announced that Adrian Peter Chesters, 46, and Alexia Alexandra Molina, 18, were found at 1 am on April 8 and were taken to hospital for treatment and are now in a stable condition.

In the same statement, they announce that the body of Nathan Chester, a 14-year-old Dutch citizen, has not been found.

Reuters report that his father told the coast guard that his son had died "as he was too weak and could not survive."

Mersing district police chief Cyril Edward Nuing said that they do not believe the body of Nathan Chester is still in Malaysian waters. "Based on the movement of sea currents, as well as the time and location where the other victims were found," it is now in Indonesian waters, he said, according to Reuters.

The site reports that Indonesian authorities would take over the search for the 14-year-old.

The diving group instructor, Kristine Grodem, 35, from Norway, was found on Thursday, Reuters reports.

The group went missing on April 6 during a training dive in Pulau Tokong Sanggol, an island roughly nine miles off Johor, Southern Malaysia.

Police said they had detained the boat operator who took them to the site after he tested positive for drugs, Reuters report.

Other outlets said a urine test had identified the drug in the captain's system as methamphetamine.
