Peaches Geldof has denied stealing a dress from a shop in London's Camden Town.
Following the 22-year-old's visit to the Three Amigos store staff claimed that an item of clothing went missing.
The shop owners are believed to have tried to get in touch with the TV presenter but contacted the police after receiving no reply from her.
Detectives were waiting to question Peaches - daughter of Sir Bob Geldof - on Monday night but one line of inquiry is that the alleged theft is due to a misunderstanding between Peaches and the shop.
A Metropolitan police spokesman yesterday confirmed that the allegation was being investigated.
Meanwhile, a spokesman for the star said: "Peaches knows nothing about this incident which we strenuously deny."
