A prosecutor says Poland has charged a lawyer with dual Polish and Russian citizenship with spying for Russian military intelligence.

The lawyer is only identified as Stanislaw Sz., in line with Poland's privacy law. Polish media say he is the son of a former Russian national goalkeeper who settled in Poland in 1991 with his family.

Wlodzimierz Burkacki, head of a prosecutors' office in Warsaw, told The Associated Press on Thursday that the man was charged with spying for the Russian military intelligence, or GRU, from 2012-2014. The indictment was sent to a Warsaw court in late April. The man could face up to 10 years in prison, if convicted. Apprehended in 2014, he remains under arrest.
