A suspected drug courier has been caught at Duesseldorf airport with 33 pounds of cocaine in his luggage and German authorities have arrested nine more people in subsequent raids.

Police and prosecutors said the 35-year-old man, from Witten outside Duesseldorf, was arrested Sunday after flying in from the Brazilian city of Sao Paulo via Madrid. The cocaine was found in his suitcase.

The arrest followed an investigation into suspected drug smuggling that was launched in November. Later Sunday, police in Witten and in Bochum raided nine apartments, arresting eight men and a woman.

Authorities accuse the group of importing around 220 pounds of cocaine in total to Germany, valued at $3.9 million, as well as a smaller quantity of marijuana.
