Protesters are calling for arrests over the roof collapse of a train station that killed 14 people in Serbia

BELGRADE, Serbia (AP) — Angry protesters left red handprints at the entrances of government buildings in the Serbian capital on Sunday, only to call for the arrest of officials two days later a concrete roof collapsed at a train station, killing 14 people and injuring three.

Police formed a cordon outside the headquarters of the Ministry of Construction and Infrastructure in central Belgrade as several thousand people demanded the immediate resignation of senior government ministers, including Prime Minister Milos Vucevic.

“Arrest, arrest!” shouted the crowd. They shouted at the police officers outside the building that they were “guarding murderers” and that “their hands are bloody” while holding banners reading “Corruption Kills” and “We are all under the shelter!”

“Leave bloody hands everywhere so they know their hands are bloody. In every city in Serbia, wherever you can,” said opposition political activist Nikola Ristic.

The concrete roof that ran along the front of the train station in the northern city of Novi Sad suddenly collapsed on Friday, landing on people sitting on benches or walking through the building's entrance. Surveillance camera footage showed the canopy collapsing within seconds.

A six-year-old girl was among the dead. The three injured people, who are between 18 and 24 years old, had to have all their limbs amputated. Doctors said they were still in serious condition Sunday.

Funerals for the victims were held in northern Serbia, attended by thousands.

The station has been renovated twice in recent years. Critics of Serbia's populist government attributed the disaster to rampant corruption, a lack of transparency and shoddy renovation work. The renovation was part of a broader deal with Chinese construction companies.

“Citizens no longer have anything to lose, they are increasingly aware of that,” said liberal politician Biljana Stojkovic. “It’s sadness coupled with anger, desperation that turns into rage.”

Serbia's populist government has promised a thorough investigation. Prosecutors said they have already interviewed more than two dozen people. But critics believe that justice can hardly be served when the populists have tight control over the judiciary and the police.

Officials insisted that the roofing was not part of the renovations and suggested that it was the reason for the collapse, but gave no explanation as to why this did not happen.

The Novi Sad train station was originally built in 1964, while the renovated train station was inaugurated President Aleksandar Vucic and his populist ally, Hungarian Prime Minister Viktor Orbán, over two years ago as a key stopover for a planned express train line between Belgrade and Budapest.
