IRVING, Texas -- Cowboys running back Joseph Randle has been arrested on a shoplifting charge, accused of taking $123 worth of cologne and underwear from a suburban Dallas department store and telling a police officer he thought to himself, "all right, y'all got me," after a security guard stopped him.

Randle, who is charged with a Class B misdemeanour theft between $50 and $500, was detained Monday evening by store security and later taken to the Frisco city jail before posting bond early Tuesday, police Sgt. Brad Merritt said.

The arrest came a day after one of Randle's best games since joining Dallas as a fifth-round draft pick out of Oklahoma State last season. He had a 38-yard run and a key tackle on a kickoff in a 30-23 victory at Super Bowl champion Seattle that gave the Cowboys their first 5-1 record since 2007.

According to an arrest report, Randle was caught on video placing items later identified as a "tester" bottle of Gucci Guilty Black cologne and a two-pack of Polo underwear into a Dillard's bag after making a purchase at the store at Stonebriar Centre, about 30 miles north of Dallas.

The 22-year-old Randle was stopped by a security guard in the parking lot and later told a police officer that when he saw the "old guy," referring to the security guard, he thought to himself, "all right, y'all got me."

After getting stopped by security, Randle returned to the store and the items were recovered. The cost of the items was $123.50 before sales tax. Randle is in the second year of a four-year, $2.3 million rookie contract with a base salary of $495,000 this season.

Randle, who declined to talk to reporters in the locker room Tuesday, finished with 52 yards rushing on five carries against the Seahawks. He has 113 yards on 16 carries for the season as the backup to NFL rushing leader DeMarco Murray. Randle had 164 yards rushing and two touchdowns as a rookie last year.

The Cowboys did not respond to a request for comment over the latest off-the-field news to envelop the team. They are waiting for results of a police investigation into a sexual assault complaint filed last month against special teams player C.J. Spillman in Grapevine, another Dallas suburb.

Spillman, who hasn't been arrested or charged, has played in all six games for Dallas. Coach Jason Garrett, who wasn't available Tuesday to address Randle's arrest, has said Spillman's status won't change unless police pursue the case.
