Family-owned German investment group Haniel said on Thursday that it had transferred a 7.3% stake in retailer Metro to a Czech-Slovak investor group, after receiving antitrust clearance. Haniel said in a statement that competition watchdogs also allowed the transfer of a total of up to 22.5% of Metro shares to the EP Global Commerce vehicle of Daniel Kretinsky and Patrik Tkac, a planned deal announced in August.
