Three minors and an adult were arrested in Belgium on terrorism charges on Sunday, the Federal Public Prosecutor’s Office said on Monday.
Federal judicial police from Liège, Brussels, Charleroi and Ghent conducted searches on Sunday morning as part of ongoing investigations. Police seized phones and laptops but found no weapons.
An 18-year-old is accused of “participating in the activities of a terrorist group and preparatory acts with the aim to commit a terrorist attack,” the prosecutors announced in a press release.
The minors, aged 15-17, were questioned by a judge in Dendermonde, East Flanders, who reported concrete plans to attack a concert hall in Brussels “within a few weeks.”
The prosecutor’s spokesperson could not confirm the name of the target to POLITICO, but local media cited Le Botanique, a cultural center and music venue in the center of Brussels where concerts attract hundreds of spectators.
According to Belgian media, the suspects belong to a jihadist movement; the spokesperson declined to comment on that information.
