Prince Harry and Meghan Markle claimed they were in a "near catastrophic car chase" in New York.
The pair were in a car with Meghan's mother Doria Ragland as they attended the Ms Foundation for Women’s 50th-anniversary gala event.
The royal couple believe the pursuit could have been fatal, as it involved six blacked-out vehicles with unidentified people driving and endangering the convoy and everyone around them.

It is said that traffic violations included driving on the pavement and through red lights, reversing down a one-way street, illegally blocking a moving vehicle and driving while photographing and while on the phone.
It's alleged that while those involved were confronted by uniformed police multiple times, they continued the chase and there is footage taken from security along with other evidence to support these allegations.
A spokesperson for the Duke and Duchess of Sussex said: "Last night, the Duke and Duchess of Sussex and Ms Ragland were involved in a near-catastrophic car chase at the hands of a ring of highly aggressive paparazzi.
"This relentless pursuit, lasting over two hours, resulted in multiple near collisions involving other drivers on the road, pedestrians and two NYPD officers.
"While being a public figure comes with a level of interest from the public, it should never come at the cost of anyone's safety.
"Dissemination of these images, given the ways in which they were obtained, encourages a highly intrusive practice that is dangerous to all involved."
The group had been at the Ms Foundation for Women's 50th anniversary gala event which honoured "game-changing" grantee partners and visionary leaders committed to the organisation's mission of "advancing collective power and creating safe, just and equitable futures for women, girls, and gender-expansive people".
Meghan received the Ms Foundation's Women of Vision Award, recognising her "global advocacy to empower and advocate on behalf of women and girls".
