Panamanian authorities could arrest former head of the State Agency for Investment and National Projects Management of Ukraine Vladyslav Kaskiv, Deputy Prosecutor General Yevhen Yenin has said.

"An unexpected problem could appear in the extradition of Kaskiv to Ukraine – he could be jailed in Panama before serving time in a Ukrainian jail. I will not disclose the details because of the secrecy of the investigation," he wrote on his Facebook page late on Thursday.
