Fake designer clothing valued at more than $550,000 has been seized and several people arrested in connection with a police raid on a storage facility in Connecticut.

Officers swooped on the West Haven warehouse and confiscated a trailer load of counterfeit clothing and brand-name tags as part of a probation probe. Police also arrested eight people in New York.

Detectives investigating the case say none of those being held are US citizens. It is believed they are from Northern Africa and the Middle East.
