Vivian Yap, 15, and her mother Nicole Tsai, 42, were on a night diving trip in the Maldives when tragedy struck on Dec 17.

They were killed when a speedboat ferrying people between Maafushi and the capital Male crashed into the side of the dive boat where they were sitting.

The accident happened just before sunset, near the island of Maafushi, which relies heavily on tourism.

The speedboat was carrying four people, while the dive boat had six on board.

There were no other casualties.

It is understood that mother and daughter were trapped in their seats before rescuers arrived.

Police quoted doctors as saying that both victims were pronounced dead when they were taken to the Maafushi Health Centre, reported Maldives news site Haveeru Online.
