Ukrainian Prime Minister Mykola Azarov has said he has no doubt that the killer of three security guards from the Karavan shopping mall in Kyiv will be found and punished.

"One thing is clear, he will be found, and those who are helping him will be found and punished," the premier said during a hotline conference with the readers of the Komsomolskaya Pravda v Ukraine newspaper in Kyiv on Monday.

At the same time, the premier stressed that "the law enforcement agencies and the whole country will be grateful" to those who provide trustworthy information about the whereabouts of the suspect.

"It's obvious that we are dealing an imbecilic former boxer. Locate and isolate [the suspect] – these are the tasks set by the president and the government for the Interior Ministry," Azarov said.

As reported, a robber shot dead three employees of a private security firm and seriously wounded another one in the Karavan shopping mall on Luhova Street in Kyiv on September 26. One of the security guards saw a visitor stealing a USB flash drive from a glass case. The guard asked the man to go to the back room, where other guards were waiting. In the room the man pulled out a gun and started shooting, killing three security guards on the spot and seriously wounding a fourth. The attacker then fled the scene.

The Obolon District Police Office has opened a criminal case on the incident. The suspect was put on the wanted lists in Russia and Belarus

Executive Director of Karavan Serhiy Kyslenko promised UAH 100,000 for assistance in finding the suspect.

On October 5, Ukrainian Interior Minister Vitaliy Zakharchenko stated that the killer of three security guards from the Karavan shopping mall in Kyiv was Yaroslav Mazurok, a native of Lviv region, born in 1974, who previously worked at private security firms.
