Nicki Minaj was forced to postpone a concert in Manchester following an incident in Amsterdam. Dutch police discovered marijuana in Minaj’s bags as she was preparing to leave the Netherlands, leading to delays, according to NPR.

Promoter Live Nation announced that the performance will be rescheduled and that tickets will still be valid. “Despite Nicki’s best efforts to explore every possible avenue to make tonight’s show happen, the events of today have made it impossible,” Live Nation stated. “We are deeply disappointed by the inconvenience this has caused.”

Minaj tweeted that she was stopped at Amsterdam airport, where police found marijuana in her luggage. Cannabis is not legal in the Netherlands, though it is decriminalized and widely available. Netherlands military police spokesperson Robert Van Kapel confirmed that a 41-year-old American woman was fined and released after being caught with “soft drugs.”

Minaj suggested on Twitter that the incident was intended to make her late for the Manchester concert, accusing authorities of jealousy. The Trinidadian-born rapper is on her “Pink Friday 2” tour, with upcoming stops across Europe. She has openly discussed her cannabis consumption in the past.
