The police raided a caravan camp in the Fakkellaan in the Eindhoven district of Woensel on Tuesday afternoon. Four men have been arrested. A police spokesman said the investigation focused on drugs and weapons.
The police are searching the caravan camp, among other things, with a sniffer dog and special cameras that can take images in small spaces. There are seven police cars on site. It is still unknown whether the men are residents of the trailer park.
