Excerpt:
German police have detained an Iraqi migrant for suspected rape only days after an Afghan refugee was held in a separate rape and murder case, and the government warned against a political backlash to such crimes.
The two cases threaten to fan anti-migrant sentiment in Germany, which saw a record 890,000 people from the Middle East, Africa and elsewhere arrive last year. The anti-immigrant Alternative for Germany (AfD) party has grown in support while Chancellor Angela Merkel's popularity has suffered.
Police said on Tuesday the Iraqi, 31, was detained in his refugee hostel on Monday on suspicion of raping a Chinese student and attempting to rape another in the western city of Bochum.
