German chancellor Olaf Scholz condemned the Munich car attack and warned that the perpetrator "cannot assume that he will be able to remain here."
A vehicle was driven at a trade union demonstration, injuring at least 28 people, in what authorities believe was an attack on Thursday, 13 February.
The suspect, a 24-year-old Afghan asylum seeker, was arrested after officers fired a shot at the car, deputy police chief Christian Huber said.
According to a translation read out by Sky News, Mr Scholz said: "The government will be starting flights back to Afghanistan despite the lack of diplomatic ties.
"He must be punished and he must leave the country."
