Robert Van Kapel, a spokesperson for the Netherlands military police, would only confirm that they arrested a 41-year-old American woman for "exporting soft drugs." He did not identify her or the drugs.

Minaj shared a video of authorities asking to search her bag. In another video, a police officer can be seen telling her she is carrying drugs, which she denies.
"Now they said they found weed & that another group of ppl have to come here to weigh the pre-rolls," she posted.
Minaj said the "pre-rolls" belonged to her security guard and that her bags had been searched "without consent."

Many messages of support from fans poured in on X, as the hashtag #FREENICKI was trending.
