A 34-year old woman was fatally stabbed by an as-yet unidentified man in the centre of the east German city of Zittau on Tuesday evening.
After the attack, the woman was taken to a nearby hospital to be treated for serious injuries, and died early Tuesday morning.
A 52-year old man has been arrested on suspicion of having committed the attack, according to police.
Police have not yet revealed the background of the suspect and victim, nor the motive behind the attack. The Sächische Zeitung reports though that both victim and attacker were German citizens and that they knew one another.
A string of bloody attacks have led to concerns in Germany about a rise in knife crime, and also given way to right-wing critics of Chancellor Angela Merkel, as some of the culprits have been teenage refugees.
In several of the attacks, the victim was apparently known to the attacker. On Tuesday, a teenage girl was stabbed to death in broad daylight by a teenage boy, suspected to be her ex-boyfriend, in the town of Viersen, North Rhine-Westphalia.
