On Thursday, three young suspects were arrested in Antwerp over what prosecutors said were plans for a terrorist attack against politicians, including the Flemish nationalist De Wever, who used to be the city’s mayor.
Investigators are probing evidence of plans to use a drone to carry an explosive device as part of the attack.
Maximus, a Scottish Fold, has been De Wever’s residency cat at the Belgian prime minister’s office on Rue de la Loi since late July.
An Instagram account documenting Maximus’ adventures has rapidly gained traction — and more than 62,000 followers.
