MOSCOW, September 3 (RAPSI) – Vladimir Podrezov, who face hooliganism charges for the alleged placing of Ukrainian flag on the spire of a Moscow skyscraper, has filed an appeal against his detention, Vadim Lisitsyn, Podrezov's attorney, told RAPSI on Wednesday.

On August 20, a Ukrainian flag was spotted on the spire of the skyscraper in central Moscow. The Soviet star on the spire was painted blue and yellow, the national colors of Ukraine.

Four young people with special climbing equipment were detained in the aftermath of the incident and charged with hooliganism. They face up to seven years in prison if convicted.

The suspects have pleaded not guilty. They said they were jumping from the building with parachutes when someone else painted the star and hoisted a Ukrainian flag on its spire.

Alexander Shirokozhukh, Alexander Pogrebov, Yevgenia Korotkova and Anna Lepyoshkina were placed under house arrest until October 19.

Podrezov, a 19-year-old roofer from St. Petersburg, was detained last week along with Kirill Ishutin upon the order of Moscow’s Tagansky District Court.

According to his attorney, Podrezov is not even acquainted with the rest of the suspects in the case, except Ishutin.

Moscow police are checking information about Ukrainian roofer Grigory (Grisha), also known as Mustang Wanted, who claims to be involved in the incident.
