Hollywood star Sienna Miller is facing an investigation over her fashion label's recent show in London, following many complaints from local residents. The star runs clothing label Twenty8Twelve with her sister, Savannah, and the company previewed its new Fall/Winter collection with a catwalk show at a converted dairy company in the city's trendy Camden. But the show, which took place last Sunday, caused outrage among local residents who found the road blocked by large vans carrying equipment, and rowdy spectators filling the streets. The complaints have been taken to the local Camden Council, meaning the actress could face an investigation and a possible fine over the fashion incident. Camden Council member Jonathan Simpson says, "It seems the developer or the owner (of the venue) is trying to make a fast buck. I hope Camden Council takes strong action against them."
