Simferopol, Ukraine - Ukrainian law enforcement agencies say they have no information about the whereabouts of Ukrainian President Viktor Yanukovich, who was reportedly seen in Sevastopol, a port on Ukraine's Crimean Peninsula that is the home of Russia's Black Sea Fleet.

After signing an agreement with the opposition to end a conflict that turned deadly, Yanukovich fled the capital for eastern Ukraine.

He tried to fly out of the country on Saturday, but was stopped by Ukraine's border service.

Opposition lawmaker Volodym Kurennoy said on his Facebook page that he had unconfirmed information that the president had been arrested in Crimea.

Ukrainian news portal reports that Sevastopol residents saw Yanukovich in the company of Russian Marines.

Spokesmen for the Interior Ministry and Security Service in Crimea said on Monday they had no such information.
