This June 2017 video says about itself:
Translated from Dutch NOS TV today:
A 61-year-old man from Barendrecht was arrested because, according to the police, he threatened a Rotterdam local council election candidate on social media. The target is a member of the Ubuntu Connected Front, which in the city council mainly wants to represent Rotterdam people with an African and Caribbean background.
UCF, which already expected racist or discriminatory reactions in election time, immediately reported the threats to the police. “The suspect could quickly be tracked down by the police’s fast actions”, says the UCF.
