Several people were injured today in the southern German city of Munich by a man wielding a knife who fled the scene, said police, adding possible motives were unknown.
A man "injured several people with a knife" in the centre of Munich and "is still on the run", the local police said on their Twitter account.
"We are searching for the perpetrator of the attack with all available police", said the statement, which added that for the moment the possible motives for the attack remained unknown.
According to the online edition of the daily Bild, none of the victims suffered life threatening injuries.
On Friday, a 27-year-old Pole knifed one person to death and injured seven others in a busy shopping centre in the southern city of Stalowa Wola that police did not immediately qualify as terrorism.
The attack occurred around 3 PM local time (1300 GMT) before shoppers apprehended the knifeman, identified only as Konrad K, and handed him over to police.
"The man acted irrationally, stabbing people in the back. One of the wounded women died. Seven other people are injured," police said in a statement.
Officers said the man had no criminal record and was sober. He is being tested for drugs.
Such attacks are extremely rare in Poland, an EU country of 38 million which has so far escaped the terrorism-related carnage experienced elsewhere in the bloc in recent years.
"The police are trying to establish the circumstances of the incident and above all, the reasons behind it," government spokesman Rafal Bochenek told the Polish PAP press agency.
