This video from Germany says about itself:

21 October 2017

An unidentified knifeman has attacked and wounded several people in downtown Munich, local police reported, adding that the perpetrator is still at large.

Meanwhile, the perpetrator is no longer at large, the suspect has been arrested.

From Reuters news agency, 21 October 2017:

German police rule out terrorism in Munich knife attack

That knife attacker had injured eight people.

According to daily The Independent, the perpetrator is ‘a blonde man in his 40s’.

I have the feeling that if the attacker would not have blonde, but black hair and/or would have been called Muhammad and/or would have been a refugee, police in Bavaria would not have declared that soon that he was not a terrorist.
