A man armed with a knife has attacked passengers on a bus in the northern German city of Lübeck, wounding several people, one seriously, police say.
A 34-year-old local man was arrested and taken into custody. Police said there was no indication the suspect had been politically radicalised.
They said on Twitter that 10 people were known to have been hurt.
Local media reports put the number at 14. An area around a bus stop in the city's Kücknitz neighbourhood was sealed off.
Police said a smoking backpack was found in the bus, containing a "fire accelerant" but no explosives.
181 is the 42nd prime number
433 is the 84th prime number
The
attack took place at 13:47 local time (11:47 GMT). An eyewitness told
the local Lübecker Nachrichten newspaper that a passenger had just given
up his seat for an older woman, when the attacker stabbed him in the
chest.
The bus driver pulled over to the side of the road and passengers fled.
Police said the suspect was overpowered by officers at the scene.
