Police were searching for vandals who painted 11 swastikas on some of the 2,700 gray slabs of Berlin's Holocaust memorial, on Saturday.
A police statement said the red and black Nazi symbols were discovered by a guard at the monument and were immediately wiped off the seven slabs affected.
The memorial to the Holocaust's 6 million Jewish victims is a field of gray slabs situated close to Berlin's Brandenburg Gate.
The vandalism discovered on Saturday came a week after a memorial to gay victims of the Nazis was also damaged.
