And speaking of random stranger-on-stranger violence:
Two female students at the University of Bochum were ambushed and raped in August and November of this year. One of them was a 27-year-old Chinese exchange student; the rape prompted the Chinese embassy to issue a travel warning. The other victim, 21, was beaten so severely that the police assumed that the rapist intended to murder her. Apparently the police sketch (above) and DNA both played a role in his arrest.
Bild reports that the suspect is a 31-year-old Iraqi migrant living in a refugee shelter.
