The Eastern Promises star was watching a San Lorenzo match on his laptop while waiting for a flight at Dulles airport, when he became excited that the team scored a key goal.
Mortensen, who was raised in Argentina, described in a column for San Lorenzo's website that he was soon confronted by security offers.
"I screamed GOAAAAAAL with all my soul, and started jumping around the place like a frightened dear among the passengers and their suitcases," he wrote. "People can't understand why am I screaming [a player's nickname] 'PIPI!' over and over again, and whether it's because I've pissed myself or maybe I got hurt someway."
He continued: "In the last extra 4 minutes added by the referee, two police men grab me and take me away from the computer, saying 'Sir, what is WRONG with you???' The cops ask for my passport and boarding pass, they ask me lots of questions. I tell them that it's OK, that I'm sorry, that I'm watching a soccer match and my team has just scored a very important goal and the match is about to end.
"And while they're asking me all these things and revise my papers all I'm trying to do is to look over their shoulders at the laptop screen, to see if the match ended with a 3 – 2 score."
Mortensen went on to reveal that he was eventually released without further incident.
"The match ends and I want to scream for victory, but I know that's not a good idea right now with these guys searching me," he recalled. "Finally, they let me go and warn me that if I start screaming again I won't be allowed to board and they'll kick me out of the airport."
The star has been a devoted fan of football since his younger years and has also supported the Argentine and Danish national teams.
