Socialite Tara Palmer-Tomkinson has been cautioned by police after a "disturbance" at Heathrow Airport.
The 42-year-old "It girl" was arrested by armed officers following her reaction to being refused access to a first-class lounge, The Sun said.
Video footage filmed by a witness showed her sobbing, swearing and tearing out her hair extensions during the incident on Saturday, the newspaper said.
Palmer-Tomkinson, who has battled drug problems in the past, was taken to a west London police station and accepted a caution under the Public Order Act.
Following her arrest, the former reality television star told The Sun that a panic attack triggered her behaviour.
She said: "I wasn't drunk, there was no disorderly. I was cautioned , I saw a doctor, they were nice to me."
Palmer-Tomkinson has since flown to Switzerland, where she will celebrate her 43rd birthday, the paper said.
A Scotland Yard spokesman said: "Police at Heathrow Terminal 5 were made aware of disturbance in the forecourt of the building at approximately 3.30pm on Saturday, December 20.
"Officers arrived at the scene and arrested a 42-year-old woman.
"She was taken to a west London police station and subsequently accepted a caution under section 5 of the Public Order Act 1986."
