A French news agency reported that a boy's body was found by bathers in the water south of Porquerolles at around 5pm. Toulon prosecutor Xavier Tarabeux told Agence France Presse (AFP): "The body matches that of the young boy who went missing on Saturday."
He said the physical appearance matched as well as the clothes. The agency reported that the body was found by Langoustier bay to the south of the island, not far from where Pierre's bike was discovered.
It said the fire and rescue service have been dispatched to recover the body. Mr Tarabeux told the agency that a post mortem examination would take place as soon as possible.
