The Industrialny District Court of Dnipropetrovsk has rejected all petitions lodged by lawyers for those suspected of committing terrorist attacks in Kharkiv, Zaporizhia and Dnipropetrovsk and scheduled the consideration of the case for November 27.

As reported, on April 27, 2012, four explosions occurred in a one-hour period in Dnipropetrovsk, injuring 31 people, including 10 teenagers, with 26 people being hospitalized. All the explosive devices were planted in concrete trash containers. The Security Service of Ukraine (SBU) investigated into a criminal case opened by the Prosecutor General's Office of Ukraine (PGO) under Part 2 of Article 258 (terror act) of the Criminal Code of Ukraine.

On May 31, 2012, senior officials in the Interior Ministry of Ukraine and the PGO stated that two suspects had been arrested for allegedly demanding $4.5 million, otherwise they threatened to continue the explosions. It emerged on June 1, 2012 that four people were arrested. All of them have been remanded in custody by the court while the investigation was ongoing.

The SBU also suspects the detainees of being behind three more terrorist attacks in Kharkiv, Zaporizhia, and Dnipropetrovsk in 2011.

In particular, on October 13, 2011 a blast went off near a kiosk in Kharkiv. On October 21, 2011 a blast hit a supermarket in Zaporizhia. Several weeks after that, on November 16, 2011, a concrete waste bin went off on Karl Marx Avenue, as a result of which a local businessman was killed.
