Prosecutors say an Eritrean man has been arrested over the fatal stabbing last week of a compatriot in the German city of Dresden, a killing that came amid tension over immigration in the region.

Jan Hille, a spokesman for Dresden prosecutors, said on Thursday the arrested 26-year-old lived with the victim and is suspected of manslaughter, news agency dpa has reported.

The victim, a 20-year-old asylum seeker, was found dead on 13 January outside the suburban apartment building where he lived. An autopsy showed he died from stab wounds to the neck and chest.

Dresden has drawn attention lately because of weekly rallies by a group that opposes what it calls the “Islamisation of the west” and advocates tougher immigration rules. Local officials have warned against jumping to conclusions regarding the killing.
