It was…in the town of Sliedrecht, that Mark Jongeneel (28) got a very disturbing phone call. His mother was on the line, worried that two policemen were looking for him, but would not say why. …the police came to his office and told him: “You tweet too much. We have orders to ask you to watch your tone. Your tweets may seem seditious.”

In Sliedrecht there had been a citizen meeting about a refugee center in the region. At the end, Jongeneel had posted a few tweets. One said: “The College of #Sliedrecht comes with a proposal to take 250 refugees over the next two years. What a bad idea! “Earlier he had also tweeted:” Should we let this happen?! ”

In recent months, police have visited the homes of many more people that criticised the plans for asylum centres.
