Those arrested may be charged with terrorism, public broadcaster Polish Radio’s IAR news agency reported, citing Czech public radio.
The detentions were made at night by officers from the National Centre for Combating Organized Crime in various locations across the country, the Czech public radio broadcaster reported, as cited by IAR.
Local police confirmed the crackdown was carried out, but provided no details, the IAR news agency added.
Officers said the case was not related to recent disclosures about explosions at an ammunition depot in the Czech Republic’s southeastern Moravia region in 2014.
Prague on Saturday announced the expulsion of 18 Russian diplomats over suspicions that Russian military intelligence officers were involved in the 2014 explosions.
