Tara Palmer-Tomkinson, 41, was detained after a pair of “killer heels” were found in her luggage as she was preparing to head back to London on Sunday after a ski trip at Klosters, the mountain resort in the canton of Graubünden.
Customs agents were concerned about the high-heel shoes, which turned out to be Chanel designer creations of Karl Lagerfeld.
The 90-millimetre heels of the shoe are designed to look like pistols, which is what concerned the agents.
“Was arrested at Zurich airport with my Chanel killer heels in my luggage,” Palmer-Tomkinson tweeted.
“Not a good look on the x ray!!” she said in her tweet.
She added that she spent seven hours waiting for luggage to be examined, a period during which she played backgammon with police officers.
The British socialite, television personality and writer is a regular visitor to the Swiss ski slopes.
Her father was ski instructor to Prince Charles, who became her godfather.
Four years ago, Palmer-Tomkinson experienced the same problem with the same shoes, 20 Minutes reported online.
That time, however customs officials waited five days before returning them to her.
The activities of Palmer-Tomkinson, who comes from a wealthy English family of landowners, are regularly documented in the social pages of British tabloids.
A former cocaine addict, she received extensive coverage when her nasal septum, the part of nose separating the two nostrils, collapsed as a result of her drug habit, leading to reconstructive surgery, according to Sky News.
