Reliant Stadium on List of Threatened Stadiums

A U.S.-based Web site claims that seven NFL stadiums have been targeted fof attacks with radiological "dirty" bombs this weekend. However, the U.S. Department of Homeland Security has expressed doubts about the authenticity of the threat, which was posted on October 12th as part of an ongoing Internet conversation titled "New Attack on America Be Afraid." The threat specifically mentions stadiums in Houston, New York, Miami, Atlanta, Seattle, Oakland, and Cleveland, where games are scheduled for this weekend.

Russ Knocke, a spokesman with the Department of Homeland Security says there's no intelligence that indicated such an attack was imminent. He says the alert comes "out of an abundance of caution."

"The department strongly encourages the public to continue to go about their plans, including attending events that involve large public gatherings such as football games," Knocke said.

The FBI also expressed doubt about the threat.

The Texans will face the Jacksonville Jaguars at Reliant Stadium on Sunday. Texans spokesman Tony Wyllie says the team has been in contact with the NFL regarding security. NFL spokesman Greg Aiello says stadiums around the country are well protected through comprehensive security procedures. Those include secure facility perimeters, pat-downs and bag searches.

Shea Guinn, President and General Manager of SMG-Reliant Park, had this to say about the security threat:  "We have and continue to maintain a good, working relationship with both local and federal law enforcement agencies, and based on the Department of Homeland Security's statement; they have judged that there is not a credible threat to the greater Houston area. As we do with all of our events at Reliant Park, we are working with our law enforcement officials and DHS to ensure a safe environment for all fans, players and gameday employees. For the safety of the facility, our policy remains that we are not able to disclose any detailed security procedure or information."
