With Super Bowl XLV just three weeks away, authorities in charge of security are dealing with their first test.

Last week, an NFL employee's car was broken into and a laptop computer was stolen. Investigators say the computer contained images of artwork for Super Bowl pre-event and event credentials.

The security credentials on the stolen notebook's hard drive had not yet been issued. The burglary forced the NFL to create new artwork.

"The NFL security credential for the Super Bowl has multiple layers of fraud prevention including the unique artwork, and the credentialing process has not been compromised in any way," said Arlington police Assistant Chief Will Johnson, the event's regional public safety planning committee chair.

Detectives said the missing computer, which was recovered, does contain other documents, and emphasized that Super Bowl public safety plans have not been compromised.
