The Higher Public Prosecutor's Office in Novi Sad announced on November 21 that 11 people were arrested after being found responsible for the deadly collapse of a concrete canopy at the railway station in Serbia's second-largest city.
The huge canopy collapsed on November 1, killing 15 people and seriously injuring another two.
The accident occurred after the railway station, built in 1964, had been renovated twice in recent years by a consortium of four companies -- China Railway International and China Communications Construction, France's Egis, and Hungary's Utiber.
Among those arrested are former Construction, Transport, and Infrastructure Minister Goran Vesic, and the ex-director of Railway Infrastructure, Jelena Tanaskovic.
They face charges of committing criminal acts against public security, endangering the public, and irregular construction work, the prosecutor said in a statement, adding that they faced up to 12 years in prison.
The arrests came after public protests that turned violent demanded the punishment of those responsible amid accusations of corruption that resulted in substandard renovation work on the railway station.
In a message on X, Vesic wrote that he had not been arrested, but had "voluntarily responded to the call of the police officers" and "made himself available to police authorities."
Vesic, an official from the ruling Serbian Progressive Party, resigned after the accident on November 4 but said he did not accept blame for the accident.
Tomislav Momirovic, who headed the Construction, Transport, and Infrastructure Ministry from 2020 to 2022, submitted his resignation as trade minister on November 20.
The same day, Tanaskovic resigned as head of Serbian Railway Infrastructure.
Opposition politicians have voiced scepticism about the arrests and demanded that the case be handed over to organized-crime prosecutors.
