The death toll of the horrible Romanian nightclub fire that happened during a Goodbye to Gravity record release has reached 32 as the three club owners at the Bucharest nightclub Colectiv have been arrested. Costin Mincu, Alin George Anastasescu and Paul Gancea were arrested for 24 hours on charges of suspected manslaughter, the BBC reports. The 32 deaths (which could rise, as many of the 180 injured are in intensive care) have sparked days of protests throughout the city, with thousands marching towards the government headquarters to demand resignations, Reuters says. An estimated 15,000 people marched on Tuesday night, demanding the resignation of Prime Minister Victor Ponta and deputy prime minister Gabriel Oprea, as well as the mayor of Bucharest.

While there might not be any federal reaction in Romania, in the wake of the tragedy, some Romanian nightclubs are addressing the lax fire codes that have plagued the country. Another Bucharest venue, Expirat, has permanently closed, The Guardian reports. “I apologise and I take responsibility,” owner Andrei Sosa said. “From 2003 I have put the lives of thousands of people in danger, weekend after weekend and sometimes during the week.” Several other venues, La Baza in Iasi and Rockstadt in Brasov, apologized for not meeting the minimum safety requirements, and Rockstadt said they would be closing for ten days to replace flammable foam and install sprinklers. Goodbye to Gravity singer Andrei Galut’s family has stated that while he’s responded to treatment, he’s still not in good condition.
