Relatives of coronavirus victims filed the first fifty lawsuits in what was dubbed 'Lawsuit Day' in Bergamo, on Wednesday.
Families rallied outside Bergamo's courthouse with documents and photos of their loved ones, before entering the building alongside one of the lawyers assisting them.
Many said they were looking to find out what happened during the coronavirus outbreak and why residents in Bergamo were not provided with hospital assistance.
Prosecutors are now investigating over the delay in the implementation of northern Italy's coronavirus 'red zone,' an area including some of the towns hit hardest by the virus.
Lawyer Consuelo Locati described the 'red zone' as the common thread of the class action, as the failure to declare a red zone allegedly resulted in an increased death toll.
Locati also asked to meet Italy's President Sergio Mattarella on his upcoming visit to Bergamo on June 28.
According to official data, Italy's northern Lombardy region, where Bergamo is located, has recorded over 3,000 deaths and more than 13,000 coronavirus cases since the beginning of the outbreak.
