MOSCOW, November 22 - RAPSI, Saria Kiut. The Moscow City Court will hear on Monday Sergei Gromov's appeal against his arrest in the case of the kidnapping of software mogul Yevgeny Kaspersky's son, the court representative told RAPSI on Thursday.

Gromov's arrest was extended by the Presnensky District Court in Moscow.

The investigation has determined that Nikolai Savelyev, his son, who is also named Nikolai, Sergei Gromov, Oleg Mayukov and Alexei Ustimchuk followed the CEO's 20-year-old son Ivan Kaspersky as of March 2011. They identified where he studied and worked, and also mapped out his daily schedule. Later, they decided to kidnap the young man in Strogino.

The Investigative Committee reported that the suspects grabbed the young man on April 19, 2011, threw him into their car, and handcuffed and blindfolded him. They then drove him to an undisclosed location in the Moscow Region where he was held until his release on April 24, 2011.

After speaking with his parents, the kidnappers agreed to prove that the young man was still in good health. The Savelyevs and Ustimchuk were arrested later that same day. Gromov was detained earlier.

Three of the men had prior convictions. A criminal case has been opened against them on charges of kidnapping and extortion, they face up to 15 years in prison.
