A man from Dordrecht has been told he will be jailed if he writes more than two letters of complaint to the city council a month.

The council had gone to court urging action against Mustafa Karasahin who sends officials dozens of complaint letters and freedom of information requests a month.

Karasahin is angry that the council has put a sequestration order on some of his properties because he is refusing to meet tougher new rules on rental properties.

Magistrates had earlier banned Karasahin from sending more than 10 letters a month to the council but he has refused to comply. So far this year he has sent officials 440 letters, all of which have to be dealt with.

Dordrecht says answering the post is costing €500,000 a year and involves 2.5 full time officials to deal with the correspondence.
