Mr. Vichai, 60, was among five people killed in the crash of the helicopter outside the stadium following Leicester City’s game against West Ham United.

The police released the names of the other four people who they believe also died in the helicopter crash: two members of Mr. Vichai’s staff, Nursara Suknamai and Kaveporn Punpare; the pilot, Eric Swaffer; and another passenger, Izabela Roza Lechowicz.

No one else was believed to have been injured.

Air accident investigators in Leicester said this past week that flight data and voice recordings had been successfully downloaded from the helicopter’s “black box.”

The Air Accidents Investigation Branch said it had been able to obtain information from the black box even though it was subjected to “intense heat” in the fire.

Inspectors have started to analyze the data to determine what caused the aircraft to spiral out of control shortly after takeoff.

The wreckage was removed from the crash site late Thursday.

Leicester players have expressed their sense of deep loss, with striker Jamie Vardy writing on Instagram of Mr. Vichai: “To me you are legend, an incredible man who had the biggest heart, the soul of Leicester City Football Club. Thank you for everything you did for me, my family and our club. I will truly miss you … may you rest in peace …#theboss.”

Leicester and England defender Harry Maguire wrote on Twitter how Mr. Vichai had supported him at the club and at international levels during the World Cup, describing the Thai billionaire as “a truly great, kind, loving man who will be missed so much by everyone.”
