Investigators say Linh, an employee of boat operator Minh Huy PQ Travel Co., assigned Nguyen Hong Hai, 57, to pilot the speedboat AG-26751 despite him not holding the qualifications required to operate it.

The boat overturned in waters off Hon May Rut Ngoai, in the An Thoi area of Phu Quoc Special Zone, on July 11, throwing all 36 people aboard into the sea.

21 were rescued and 15 Indian tourists died.

Police are continuing to investigate the cause of the capsizing and the conduct of others involved.
