Police inspected 13 vacant houses and questioned five people during a large-scale operation in Luxembourg City, police said. The checks took place last Friday, with 12 officers focusing on uninhabited properties in Hollerich, Gasperich, Limpertsberg, Kirchberg and Ville Haute. In total, officers searched the so-called squats at the different addresses and spoke to five people found on site. Police said the operation was targeted at enforcing immigration laws and maintaining a visible police presence. The five people were questioned at the scene, and the police action was carried out as part of an ongoing enforcement effort.
