Police have reportedly apprehended a suspect after a knife attacker wounded multiple people in Munich.

Authorities launched a manhunt after six people were attacked on Saturday morning in the Rosenheimer Platz area of the Bavarian capital.

Four people are thought to be injured but none sustained life-threatening injuries, according to authorities.

Munich police spokesman Marcus da Gloria Martins said: "We have arrested a person who very strongly resembles the description by witnesses, but we cannot confirm that he is the attacker."

Earlier, Munich police urged residents to stay indoors while the attacker remained at large.

The suspect was described as an unshaven, "corpulent" man in his 40s, with medium blonde hair.

He was reportedly wearing grey trousers, a green jacket and a backpack with a rolled up sleeping mat and fled the scene on a black bicycle.

Munich police said they had received conflicting reports of the direction in which the attacker fled.

It was unclear whether the man arrested is the same man in the police descriptions.
