A factory which made 41,000 fake Apple iPhones has been raided in China.

The counterfeit iPhones, which were assembled using second hand smartphone parts, were worth a reported 120 yuan ($19m).

The raid, which has been months in the planning, discovered "hundreds" of workers making the phones.

Beijing authorities said the factory was run by a husband and wife team on the northern outskirts of the city.

US authorities alerted Beijing to the fake iPhones after seizing several handsets. The two have agreed to work together to tackle the growing number of fake goods produced and distributed between the countries.
