Jakarta. Police announced three suspects charged with an explosion and fire at a fireworks factory in Tangerang, West Java, on Thursday (26/10) that killed 47 people and injured dozens others. One of the suspects is the owner of the warehouse.

Jakarta Police Argo Yuwono said the police had conducted a thorough sweep of the crime scene and interrogated several witnesses on Friday.

"We now have three suspects: the owner of the factory Indra Liyono, operational director Andri Hertanto and a welder, Subarna Ega," Argo said in a press conference.

The suspects have been charged with causing death by negligence which carries a maximum sentence of five years.

International Labor Organization (ILO) on Friday urged the government to do more to enforce its workers' health and safety regulation (K3).

"ILO will work with the government, labor organizations and businessmen to explore how to improve work safety and prevent similar incidents from happening in the future," ILO Indonesia Director Michiko Miyamoto said.

According to the organization's data, 1.8 million work-related deaths happen every year in the Asia-Pacific region, two thirds of them in Asia.
