Rioters set fires in the centre of the southern Dutch city of Eindhoven and pelted police with rocks Sunday at a banned demonstration against coronavirus lockdown measures.
Officers responded with tear gas and water cannons, arresting at least 30 people.
The country has been in a tough lockdown since mid-December that is due to continue at least until February 9.
Trains to and from the station were halted and local media reported plundering at the station.
There were no immediate reports of injuries.
