The man who was forcibly dragged off a United Airlines flight in Chicago has begun the process of legal action against the airline.
This week, video footage of Dr David Dao being violently removed from United flight 3411 went viral on social media, sparking global outrage and fury.
The airline had attempted to remove the 69-year-old and three others from the Chicago-Louisville flight in order to make room for cabin crew, who had to be at the Kentucky airport for a follow-up flight.
The CEO of the company, Oscar Munoz, apologised to Dao for the incident, but the doctor has filed an emergency request in an Illnois court for United to preserve any video footage of his removal from the flight.
The request seeks to avoid a risk of 'serious prejudice' to Dao by ensuring all records pertaining to the incident and flight 3411 are not destroyed.
The 69-year-old - who is recuperating in a hospital in Chicago - and his family released a statement via their lawyer to thank the world for the "outpouring of prayers, support, and concern" they are receiving in the wake of the incident.
