The three suspects could each face five years in prison if found guilty of negligence leading to deaths....

The business was operating from a house in the North Sumatra district of Langkat and reportedly made match sticks and lighters.

Its female employees were trapped in Friday's blaze by a locked door. Five children died in the inferno and only four people escaped, Atmaja said.
