During the autumn Carl Philip was working as a trainee with photographer Mattias Klum. The prince followed Klum and documentary film-maker Folke Rydén on a journey in the footsteps of Swedish scientist Carl von Linné.
Because he had left his passport behind at a hotel in the town of Ciudad Guyana, the prince ended up leaving Venezuela on a later flight than the rest of the film team. His security guards deemed it safe for him to arrive in the USA unaccompanied.
But Carl Philip arrived in Miami without a work visa and, as a result, wound up spending the evening in police custody, Aftonbladet reports.
Passport police did not believe him when, having politely waited in line with the other passengers, he told them he was a Swedish royal and displayed his diplomatic passport.
“As I understand it he was taken aside for questioning and missed his connecting flight.
“I got the impression that he thought it was quite exciting,” said Folke Rydén.
The prince eventually caught up with the rest of the crew in Washington a day later than anticipated.
A spokeswoman for the royal court, Nina Eldh, has poured cold water on the newspaper’s claims.
“I spoke to the prince today and nothing unusual happened when he got to Miami,” she told Aftonbladet.
