At least 28 people have been injured after an Afghan asylum seeker drove at a crowd of people in Munich, police say.
People had been gathering at a trade union rally when the car accelerated in their direction. An officer fired one shot at the suspect before he was arrested - he was injured, but sustained no gunshot wounds.
Police say no other people are known to have been involved.
The suspect - named locally as 24-year-old Farhad N - came to Germany in 2016, according to reports. He had his asylum application rejected, but his deportation was suspended.
Counter-terrorism police have taken over the investigation due to indications that the suspect has an "extremist background", say police. BBC Verify has been looking into his social media presence.
The attack comes as the city prepares to host the Munich Security Conference this weekend. Authorities do not believe this incident is related to the event.
And, with just 10 days to go before a national election, the profile of the suspect will add to an already fevered debate about migration, writes the BBC Berlin correspondent Damien McGuinness.
German Chancellor Olaf Scholz, alongside other politicians, has responded harshly to the incident.
"This perpetrator cannot hope for any leniency. He must be punished and he must leave the country," Scholz told reporters.
