Detectives from the police’s organised crime unit raided Czech Post headquarters on Prague’s Politických vězňů and Olšanská streets on Tuesday. Officers arrived at the postal service’s buildings at 6 AM. The state attorney said the raids were linked to an investigation launched in January concerning the manipulation of building contracts; it has now been extended to include a transport contract. A total of 15 people have been charged to date, while four companies are under investigation, including Czech Post. The two post offices have remained open to the public.
