The kidnapped son of a Russian software tycoon had been freed unharmed by Russian special forces, police and the tycoon's company said Monday.
Police spokesman Viktor Biryukov told Russian television that intelligence officers and OMON special forces took part in the operation to free 20-year-old Ivan Kaspersky. Five people were detained on suspicion of kidnapping.
Kaspersky Lab, which is owned and managed by his father Evgeny Kaspersky, said in a statement that no ransom was paid. It said Ivan is now in a safe place.
Ivan Kaspersky was kidnapped by unidentified men outside his mother's office where the mathematics student was doing an internship.
His parents were not available for comment Monday.
Evgeny Kaspersky's business is a rare story of Russian global business success outside the energy sector. The Forbes magazine estimates his fortune at $800 million.
