The organiser of a party at a water park in Taiwan, where an explosion killed 15 people last June, has been found guilty of negligence.
Lu Chung-chi, the owner of Colour Play Asia, was jailed for four years and 10 months.
More than 500 people were also injured at Formosa Water Park outside Taipei when a coloured powder which was being sprayed over the crowd ignited.
Taiwanese media said Lu could appeal against the conviction.
Most of the victims of the 27 June disaster were young people, some of whom were left with 90% burns.
Video footage showed people dancing in front of a stage and cheering as clouds of green and yellow powder covered them.
The powder abruptly burst into flames, engulfing partygoers in an inferno with no way of escaping.
