German police arrested a 16-year-old Afghan boy in Munich on Sunday after police found contradictions in statements the youth made to police earlier about his relationship with an 18-year-old German-Iranian, Ali David Sonboly, who shot and killed nine people in the city on Friday. “There is a suspicion that the 16-year-old is a possible tacit accomplice to [Friday’s] attack,” police said in a statement Sunday, reported by broadcaster Deutsche Welle.
