THE HAGUE: Dutch police called Saturday on more than 20,000 men to come forward with DNA samples in a bid to catch the perpetrator of the murder of a young boy 20 years ago.
"The doors of six sampling sites are open!" the police force in the southern Limburg province said on Twitter.
Around 21,500 males aged between 18 and 75 now have three weeks to voluntarily submit their DNA for testing as part of the reopened probe into the murder of Nicky Verstappen, 11, in 1998.

Dutch police said the men asked to volunteer DNA were not suspects in the case, stressing that the operation was primarily aimed at pinpointing if any donor is related to an unknown person who left traces of their DNA on Verstappen.
Analysis of the samples is expected to take between six months and a year.
