Amsterdam police said there was "no indication whatsoever" of terrorist involvement in an incident Saturday in which eight pedestrians were struck and injured by a car.
The car was parked illegally near Amsterdam Central Station, the city's main rail terminal, police said. When officers approached the driver, the car lurched forward into a retaining wall, striking several pedestrians.
The police later tweeted, after speaking with the driver, that the incident appeared to have been unintentional. They said the driver had apparently been ill, but he was arrested.
Six of the injured people were hospitalized, a police spokeswoman said, adding that two were in serious condition.
Attacks over the past three weeks in England, beginning with a deadly suicide bombing at a concert hall in Manchester, and other terror-related incidents have put authorities in many European countries on high alert.
