Up to $1.7 million worth of fake designer clothing has been seized by police and six people arrested during a series of raids in northern Italy.

Officers said they had found 54,000 items of clothing, ranging from jeans and shirts to coats, jackets, T-shirts and scarfs, in several warehouses near Milan.

The counterfeit apparel included fake labels for famous brands such as Armani, Lacoste, Ralph Lauren, Burberry and Prada.

Police said they also seized more than a million fake tags, buttons and labels and added that the haul had been destined for markets in Italy.
