A French diver drowned in Xwejni Bay, Gozo, after finding himself in difficulty yesterday morning, police said.
The 59-year-old tourist was pulled to the surface by the group of divers he was with around 11.30am.
It is not yet known whether he suffered a heart attack under the sea. The diver was certified dead on the spot.
A magisterial inquiry is under way.
Two other French tourists also died in Xwejni Bay two months ago after strong winds produced storey-high waves.
