German police have raided the homes of more than 300 people suspected of posting neo-Nazi music files on the internet.
Neo-Nazis try to tempt young people with their music, police say
Police say they have seized thousands
of compact discs and hundreds of computers in their nationwide raids.
Federal Crime Office President Joerg Ziercke warned neo-Nazis used skinhead music to reach out to young people.
"Young people are being targeted and brought into the world of anti-Semitism and hatred of foreigners," he said.
"Inciting racial hatred is more than just a petty crime."
Police sources said the raids were part of their ongoing investigations into 342 people suspected of posting songs by skinhead bands on music swap sites.
Some of these songs contain explicit lyrics inciting people to attack Jews and immigrants.
Publishing Nazi slogans and materials are crimes punishable by imprisonment under German law.
The recent raids follow a similar operation by German police against neo-Nazi group Combat 18.
The group, which takes its name from the position in the alphabet of Adolf Hitler's initials, has been blamed for carrying out or motivating racist attacks.
Police believe they foiled a bomb plot against a Munich Jewish centre during a visit by German President Johannes Rau in November.
