The illegal weapons were recovered by Swedish border guards from a German couple who arrived in a car marked “Zombie Response Team”.

The incident took place in March and was only publicised this week when prosecutors announced the couple would be charged with smuggling, SVT News reports.

The vehicle was singled out for a search due to its decals, which included slogans such as “infected people will be shot”.

The couple reportedly told police that they were moving to Sweden and did not know it was illegal to bring the weapons with them.
