The stabbings happened in a public park in the centre of the Bavarian city of Aschaffenburg at around 11:45 am (1045 GMT), they said.
The attacker targeted a group of children from a daycare centre who were in the park, German media reported.
The suspect, a 28-year-old man from Afghanistan, was arrested “in the immediate vicinity of the crime scene”.
German media reported that the man was said to have had psychological issues and had received treatment several times.
A second person held by police was being questioned as a witness.
Police said train traffic around the scene had been suspended, with services delayed or diverted.
