Peaches Geldof was questioned by police after allegedly starting a nightclub brawl.
The 19-year-old socialite reportedly initiated the row after throwing a shoe into the crowd of partygoers at top London venue Bungalow 8 in the early hours of Wednesday (08.04.09).
The shoe is believed to have hit a woman, whose boyfriend then came over to demand an apology, sparking the fight.
An onlooker said: "Peaches was having fun and thought it would be hilarious to send her shoe flying through the crowd. But her game backfired when it hit a woman. Her boyfriend was furious and began arguing with Peaches. Then a fight broke out."
During the brawl, a glass was thrown, which narrowly missed Peaches. The nightclub security quickly came over to calm the situation down.
The onlooker continued: "They threatened to throw the man out. Peaches was drenched and ran to the toilets to get cleaned up."
Peaches - who was with her friend Fifi Brown - is said to have demanded club bosses phone the police and get the man arrested for assault. However, when officers arrived, everyone involved was questioned and they left without making any arrests.
A Scotland Yard spokesman said: "Officers were summoned to a club in St. Martin's Lane at about 2.45am and spoke to a number of people concerning an allegation of assault.
"However, the allegation could not be sustained so no further action will be taken."
