Who's behind Europe's largest rare book heist?

The University library in Tartu, in Estonia, is a large brutalist complex, surrounded by concrete water fountains and futuristic steel sculptures. But inside this unassuming building lies a hidden treasure: rare books worth thousands. In April 2022, some of these books were stolen, including historic editions by Alexander Pushkin. According to Europol, the European law enforcement agency, this theft was part of a criminal operation that targeted national libraries in 12 countries, including the Baltic states, Poland, Finland, Germany and France. It's been described as Europe’s largest book heist since War World Two. Who was behind it? My colleague Nina Nazarova from BBC Russian has been investigating this story.
