Kanye West and Kim Kardashian West hired an illegal security escort in Arizona.

The couple is reported to have angered officials at the Phoenix Police Department after organising a small team to ride with them through the city, using flashing red and blue lights - the use of which is prohibited by non-emergency vehicles.

In a video first published by X17online, the couple's convoy, consisting of around four motorcycles and two black SUVs, could be seen making its way down the highway "displaying a red or red and blue lights," which goes against state laws.

A spokesperson for the Police Department, Trent Crump, denied that any of his officers were part of the convoy.

According to the New York Daily News, he said: "That was not done by us, but they could hire private security or off-duty officers."

He added that off-duty officers could use flashing lights "depending on department policy," though there was no stipulation as to what the conditions of their use could be.

The couple arrived in the city last week, ahead of the Super Bowl XLIX, and were spotted on a double date with John Legend and his supermodel wife, Chrissy Teigen, ahead of John's performance of America the Beautiful to kick off the Super Bowl on February 1.

The superstar foursome enjoyed a meal at a Waffle House with Chrissy later posting on Twitter: "Every house should be a waffle house."
