9:26 AM PT -- A rep for the Nobel Institute is now essentially calling out Sarah's people. The rep tells TMZ, "This individual (the shoplifter) is NOT an employee of and has no connection to the Nobel Institute, which awards the Peace Prize and presents the Peace Prize Concert. She is a freelance make-up artist who was contracted by an outside agency that specialized in that area."
8:00 AM PT -- A rep for Sarah tells us the culprit was NOT SJP's assistant, and was not on her payroll ... but was traveling as part of Sarah's entourage.
A source connected to Sarah claims the alleged shoplifter was actually working for the Nobel Peace Prize. SJP was in Oslo to host a concert for the organization.
If you were flying from Oslo, Norway to NYC on United today ... you would be plenty pissed off, because the plane was delayed for an hour while police dealt with a little shoplifting incident involving Sarah Jessica Parker's assistant.
Sources who work at the airport tell TMZ ... Sarah -- seen above arriving at the United terminal -- and her entourage were ready to board the plane when they were confronted by cops, who were called after an airport shop owner claimed one of Sarah's minions pilfered a pair of expensive sunglasses.
Police blocked the assistant from boarding and worked out a settlement of sorts -- a fine of $1,400, which was paid on the spot. We're told Sarah and the assistant then got on board and the plane took off.
That's what you get for horsing around in Norway.
