Hundreds of police and customs officers and other officials raided the largest Vietnamese marketplace in Prague on Saturday. The authorities suspect that various kinds of criminal activities take place at the marketplace in Prague-Libuš, known as Little Hanoi. Officials were looking for counterfeits, illegal aliens and wanted persons. Foreigners’ police have detained more than 40 people since the start of the raid. Czech authorities claim that criminality within the Vietnamese community in the Czech Republic is on the rise; the Czech foreign ministry recently suspended the issuing of long-term visas for Vietnamese citizens as a result.
