"I can confirm that four Ukrainian citizens were detained. They are suspected of involvement in the activities of a criminal group, money laundering and document forgery. We cannot disclose their personal data," Starak said. According to her, all four people had a residence permit in Spain. The case will soon be submitted to the court in Barcelona. "The case is classified, so it will be extremely difficult to get any additional information," Starak noted. Spanish media earlier reported that eleven people had been arrested in Spain on suspicion of money laundering. The son of ex-mayor of Kyiv Leonid Chernovetsky was reportedly among them.
