The Ukrainian Security Service has detained in Kyiv one of the top managers of a supermarket chain on suspicion of financing "DPR", the SBU said in a statement.
The detainee is suspected of financing of terrorist, the SBU said.
The detention was a continuation of the searches the SBU held in the offices and homes of a number of businessmen in Kyiv in late November.
As a part of the retail chain continued working in the "DNR", a part of profits was channelled to terrorists' organisations, including via a charity fund.
During the searches, law enforcers seized cash stashes amounting to almost two million hryvnia equivalent.
The name of the top manager and retail chain are not disclosed.
