Police deny giving Kanye West and Kim Kardashian an official escort

Officials in Arizona have denied allegations they broke protocol by giving Kanye West and his wife Kim Kardashian a police escort to the Super Bowl.

Video footage published online appears to show two motorcycles with flashing lights tailing the couple's motorcade as they make their way to the University of Phoenix Stadium for the big football game on Sunday (01Feb15).

The film sparked outrage among online critics, who accused local authorities of wasting police resources by giving a security detail to the stars, but a representative for the Phoenix Police Department has now insisted the motorcycle security convoy was nothing to do with cops.

Spokesman Trent Crump tells the New York Daily News, "That was not done by us, but they could hire private security or off-duty officers... (There are) dozens and dozens of agencies (that could provide this kind of private security)."
