One year on from a tragic Waterpark incident which caused the deaths of 22 people and resulted in more than 400 burn injuries, family members of victims have filed a lawsuit against the park owner and six others, demanding NT$2.6bn (US$80m, €72,3m, £59.7m) in compensation.

The accident, which occurred at the Formosa water park in New Taipei City on 28 June 2015, happened when a coloured corn starch cloud burst into flames, engulfing a crowd of party-goers in a massive Firestorm.

The Consumers' Foundation said it was filing the lawsuit on behalf of the family members of 22 dead and 76 injured against park owner Chen Po-ting, party organiser Lu Chung-chi and five others involved in the incident.

The sum, says the Consumers’ Foundation, covers medical and funeral bills, lost employment and productivity, and payments to support the victims' family members, with varying levels of compensation based on how badly burned each victim was or if they had died.

In the wake of the accident, the park was closed and the government implemented a ban on use of such powder at future events. Lu Chung-chi also received a jail sentence of four years and 10 months on charges of negligent homicide.
