Fire menn kom til skade, flere av dem alvorlig, da en mann gikk til angrep på reisende ved en togstasjon i München. Mannen skal ifølge vitner ha ropt «Allahu akbar» – gud er større.
A police spokeswoman said four or five commuters were wounded in the attack in Grafing, one of them seriously.
The suspected attacker was overpowered and arrested, and the authorities working to identify him believe his motive may have been «political».
Police are checking witness statements that the man shouted «allahu akbar» during the attack, which happened shortly before 5am (4am UK time) on Tuesday morning.
It is believed all of those injured in the stabbing were men.
Initial reports from a Bavarian radio station had suggested that four people were left with life-threatening injuries.
