The defendant was a consultant at several Swedish companies before he was arrested, including Volvo Cars in Gothenburg and the truck-maker Scania. He is accused of selling information from these workplaces to Russia.
"While a consultant at his former workplaces, I allege that he obtained material with the purpose of providing information to a foreign power, in this case, Russia," said Ljungqvist at the time of the accused's arrest.
The man reportedly transferred material from his work computer to his personal computer, before putting that information onto a USB memory stick to try to evade the internal IT system. He also photographed the screen of his work computer to transfer the information.
After his arrest, Sweden denied visas to two Russian envoys, and Moscow expelled two Swedish diplomats. The defendant denies the charge and the trial is expected to conclude on September 1. If convicted, the defendant may receive the maximum sentence of six years.
