WTVF-TV reported Saturday that Cook's credit card was stolen from his vehicle and then used to buy more than $3,000 worth of electronics at several Wal-Mart stores in the Nashville area.
A 19-year-old charged in the case can be seen on Wal-Mart video using the card to make the purchases, The Tennessean reported. He is charged with two counts of credit-card fraud, identify theft and forgery but has denied involvement in the case.
The other four suspects -- two 20-year-olds and two 21-year-olds -- are linked to at least four break-ins in which stolen property was recovered. Charges include theft and aggravated burglary, with additional charges expected.
Cook started one game in 2010, his second season as a pro. The 24-year-old, who played college football at South Carolina, had 29 receptions for 361 yards and one touchdown.
