Authorities have taken control of 17 websites registered in the Washington area as part of a nationwide crackdown on the sale of counterfeit goods.

The federal operation, which targeted 82 domain names, was announced on Cyber Monday, considered one of the biggest Internet shopping days of the year. Investigators believe the websites were selling counterfeit goods, including DVDs and knockoff Washington Redskins and Nationals jerseys, according to court documents.

A private investigator found that jerseys purchased during the operation were "of poor quality, material and craftsmanship, and the NFL jerseys had counterfeit marks," the documents state.

A copy of the court documents is posted below.
