A migrant man has been arrested after a stabbing rampage in a central square in Munich.
Police were called after a man injured four people and tried but failed to stab two others, in the Bavarian capital.
The victims were five men and one woman, 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,' Martins said.
Several were injured in the attack, at five locations within close proximity to each other - none thought to be life-threatening.
The attacker has been described as a North African, unshaven man travelling on a black bike, roughly 40-years-old wearing grey trousers, a green jacket and carrying a backpack with a sleeping mat.
The attack happened at 6.30GMT, near the Rosenheimer station. Police urged residents to remain in their homes while the manhunt continued.
Police also advised the public to stay away from Ostpark, which is around 2.5 miles (4km) away from the scene of the attack.
Munich police used their official Twitter channel to issue a warning urging locals to stay away from three specific areas: Ostbahnhof, Ostparkand and Rosenheimer, and remain indoors if possible.
The police tweeted following the arrest of a man: 'We were able to arrest a suspect. It is currently unclear whether it is the offender.'
And earlier said they were unclear about the attacker's motives: 'We are searching for the offender with all police officers available. Until now we know nothing about the motivation.'
Video footage shows a helicopter flying overhead searching for the attacker.
