The man German security officials call a major security risk looks like a figure from a rap video, especially with the tattoos on his hands. The right one says “STR8,” and the left one “Thug.”
“This is from the days when I lived the life of an unbeliever,” said the man, Denis Mamadou Cuspert, as he clenched his fists and looked at the tattoos. “Allah will erase them from me one day.”
Mr. Cuspert, once a popular rapper in Germany, today is one of the best-known singers of nasheeds, or Islamic devotional music, in German. Security officials say, though, that he is an influential figure who incites violence and unrest through inflammatory videos and fiery speeches that praise terrorists and attack the West.
