Lewandowski's ex-agent detained on suspicion of extortion

The investigation is focused on criminal threats against "an outstanding footballer, former client and associate of the suspect" aimed at coercing him into handing over 20 million euros ($23.67 million) to Cezary K., said Marcin Sados, a spokesman for Warsaw prosecutors, according the Polish PAP news agency.

Under Polish law, the surname of suspects cannot be made public.

Bayern Munich forward Lewandowski, 32, filed a complaint against his former representative in early October. The ex-agent also says he has filed a lawsuit against Lewandowski in this case.

Cezary K., claims Lewandowski owes him 39 million zlotys (8.52 million euros, $10 million dollars), allegedly amounting to the share price of part of a joint company created in 2014 and intended to manage the footballer's future contracts. The company has since been closed.
