There has been an increase in African prostitutes in the city, which, thanks to legal prostitution in the country, has drawn an increasing number of immigrant prostitutes that Kjeld Farcinsen of the Copenhagen Police decscribed as “increasingly aggressive.”

“When our undercover officers approach them, the women make no attempt to hide the fact that they are offering sex for money,” Farcinsen told Politiken newspaper.

Farcinsen went on to say that the city’s police will be conducting more night raids in the coming weeks, in hopes of catching more illegal prostitutes.

Prostitution is legal in Denmark and carefully monitored, but non-residents are not allowed to engage in the profession. Nigerians form the largest contingent of Africans working in the trade.
