The motivation for the attack is still unclear as the suspect refused to make a statement during his interrogation by police.
A knife-wielding man randomly attacked passersby in central Munich today, lightly injuring eight people, police said as they excluded terrorism as a motive after detaining the suspected perpetrator.
No one was seriously hurt in the attack that started at around 8.30 a.m.in the Haidhausen area, east of downtown Munich.
Local police chief Hubertus Andra said eight people, including a woman and a 12-year-old boy, suffered minor injuries in the attack near Rosenheimer Platz.
They urged people in the city to remain at home as they had received conflicting information about which way the attacker had gone.
The police department said on Twitter that officers are looking for the assailant "with all available police forces".
About three hours later, police arrested a man matching a description they had issued based on witness reports. The suspect was described as a man in his 40s who had fled the scene on a black bicycle.
But "absolutely no element" of the investigation leads police to believe it was a politically or religiously- motivated act of terror, he said.
