A van slammed into pedestrians near a campsite at a major music festival in the Netherlands on Monday, killing one person and seriously injuring three others, police said.

The driver fled following the incident at about 4:00 am  by the PinkPop Festival in the southern town of Landgraaf, near the German border.

"The van involved is still being sought," police said on Twitter.

Police have cordoned off the section of the road while an investigation is under way.

 The 49th edition of the Pinkpop festival has drawn around 67,000 fans a day since it opened on Friday, according to the director, Jan Smeets.
