Vasil Bozhkov is ready to return to Bulgaria as a Protected Witness

"I am ready to return to Bulgaria as a protected witness", Vasil Bozhkov wrote on Facebook today.

"Borissov's impudence gave way to his fear. He has reason to be afraid," he also wrote.

Bozhkov, who lives in Dubai, has been charged with 19 charges, on which more than 200 witnesses have been questioned, 18 European investigation warrants and requests for legal assistance have been sent to 17 countries. A request for his extradition to the UAE was also sent, as well as four more requests for legal aid. The last one - to appear before the Bulgarian investigators - is from this January.
