The accident occurred at 2am of the same day, when Francois and a group of his friends, who just returned to Da Nang from Hoi An ancient town, were sea-bathing at My Khe beach.
The man and his friends swam far away from the shore. While his friends could swim into the shore safely, Francois was washed away by strong currents.
Da Nang authorities sent dozens of coast guards to search for the Belgium tourist. However, until 5am, they saw the body around 300m from the shore.
In late March, two South Korean men drowned after they went into the sea for swimming at Nghinh Phong beach of the southern province of Ba Ria-Vung Tau.
