Guernsey Police said that during the course of their 15-hour search they had found a number of objects in the water but there was no confirmation that they were from the aircraft.
They added: ‘We have been unable to confirm whether any of these are from the missing aircraft. We have found no signs of those on board. If they did land on the water, the chances of survival are at this stage, unfortunately, slim.’
As of 5 pm on Tuesday, search and rescue operations were suspended due to the poor light. Guernsey police have said the current plan is for the search to resume at sunrise tomorrow.
The 28-year-old Nantes striker, who signed for Premier League side Cardiff City on Saturday, was one of two people on board a light aircraft that disappeared from radar on route from Nantes to Cardiff. He had been returning to Cardiff after saying goodbye to his former teammates in Nantes.
Rescue teams were scrambled to waters north of Guernsey after the light aircraft vanished 15 miles north of the island on Monday evening.
A major search and rescue operation was launched involving both St Peter Port and Alderney lifeboats and HM Coastguard’s Air Search 1 and 2 helicopters.
