Mexico City prosecutors said they would bring criminal charges against "several people and companies" after a subway line collapsed and killed 26 people in May.
Ernestina Godoy, the city attorney general, said the goal of the charges was to seek compensation for damages incurred by both the victims and the subway, according to The Associated Press. She did not specifically identify who would face the charges which could result in prison sentences.
Godoy also said that a review found bad design, poor welds and missing studs were among the construction defects that contributed to the collapse, per the AP.
Some of the companies that helped construct the line also added that repairs over the years that may have made the elevated line too heavy. Prosecutors added that the city's frequent earthquakes could have also contributed to damages, the AP noted. The section that collapsed has not reopened since May.
The private Norwegian certification firm DNV found results similar to Godoy's report when it released a report on the incident in September.
The collapsed line of the city's metro system cost $1.3 billion when it was constructed between 2010 and 2012. Despite the high price of the project, the line was closed in 2014 for track repairs amid design flaws and other alleged corruption.
Allegations of poor design and issues with construction first appeared shortly after Foreign Affairs Secretary Marcelo Ebrard, who served as Mexico City’s mayor at the time of the subway’s construction, left the mayor's office in 2012.
Ebrard is now considered a possible contender to succeed Mexican President Andrés Manuel López Obrador.
