The Indonesian Consumers Foundation (YLKI) has called on authorities to investigate the management of the Indonesia Stock Exchange (IDX) building in South Jakarta for their alleged negligence that led to the collapse of a mezzanine in the building and injuries to at least 77 people.

YLKI chairman Tulus Abadi said the police needed to take firm action because the incident had endangered the lives of many people. 

"We urge the police to question parties from the building management to find out whether any laws pertaining to buildings have been violated. It may indicate the party responsible has failed to properly maintain the building," Tulus said in a written statement. 

He added that he urged the party to be responsible for the victims, not only by covering for their medical costs, but also by providing compensation.

"We urge the Public Works and Public Housing Ministry to conduct a thorough inspection of all public buildings in the capital, such as shopping malls, hotels and offices, to ensure they have followed proper safety standards. The incident may have created fears among the public," he said. 

At least 77 people were injured following the incident. Several of them suffered fractures and were admitted to hospitals to undergo medical treatment. 

Authorities have yet to identify the cause of the collapse.
