One person has been killed and three seriously injured in an incident involving a van at the Pinkpop music festival in Landgraaf.

The incident happened at around 4am on a road near one of the festival’s three campsites. The van, possibly a white Fiat Doblo, drove off after hitting the festival goers. The driver was arrested later on Monday morning.

Limburg police say they do not yet know if the van deliberately drove into the people or if it was an accident. They are due to hold a press conference at midday to give more details.

Acccording the Telegraaf, Belgian and German police were also involved in trying to trace the van, which was seen by many festival goers.

The condition of the three people who were injured is said to be very serious.

The 49th edition of the festival ended on Sunday night with a performance by Bruno Mars. However, many festival goers remained on the festival campsites until Monday morning.

Jelle Gunneweg, a reporter for RTV Rijnmond, was at the festival and told NOS that activities continued on the main festival area until 3am.

People then walk back to their campsite through the normal traffic on the road, he said. ‘So at 4am you have drunk people and sober people all mixed up on the road.’
