(QHA) -

Ousted Ukrainian President Viktor Yanukovych is wanted by police for mass murder, the acting Interior Minister of Ukraine Arsen Avakov said on Monday on his Facebook profile.

"An official case for the mass murder of peaceful citizens has been opened," Arsen Avakov wrote on his profile. "Yanukovych and other people responsible for this have been declared wanted," he added.

Ukrainian law enforcement agencies said Monday they have no information about the whereabouts of Yanukovych, who reportedly was seen in Sevastopol, Crimea.

After signing an agreement with the opposition to end a conflict that turned deadly, Yanukovych reportedly fled the capital for eastern Ukraine. Ukraine's border service said he tried to fly out of the country Saturday from Donetsk but was stopped by their officials.

Tensions have been mounting in Crimea, where pro-Russian politicians are organizing rallies and forming protest units and have been demanding autonomy from Kiev. Russia maintains a big naval base in Crimea that has tangled relations between the countries for two decades.
