Nearly 2,000 officers are searching apartments and businesses in the German capital.
Berlin prosecutors say they are targeting suspected human traffickers who exploited foreign workers in the construction industry.
Police and customs officers launched a massive human trafficking raid in Berlin on Wednesday morning, prosecutors in the German capital said.
Around 1,900 officers are taking part in the operation and have searched over 100 apartments and businesses across the city, Berlin's prosecutor's office said in a statement posted on Twitter.
Authorities also searched properties in the eastern states of Brandenburg and Saxony-Anhalt.
The raids are being carried out on suspicion of "human trafficking for labor exploitation" and the "organized smuggling of foreigners into the construction industry."
Michael Kulus, a spokesman for the central customs office in Berlin, told the Germany daily Bild newspaper that the operation is expected to last the entire day and that "construction sites, businesses and tax advisor offices" are being searched to gather evidence.
Authorities did not immediately provide more details, saying more information would be made available later in the day.
