Leicester City Football Club is owned by Thai billionaire Vichai Srivaddhanaprabha.
It was his helicopter which crashed outside the stadium with five people on board.
He regularly flew in and out of the stadium to watch his club play.
He and his son ran one of the world's biggest duty free empires, King Power.
They bought Leicester in 2010 from Milan Mandaric for £39m, when the club had just finished fifth in the Championship.
In 2014, he said they would spend £180m to break into the top five within three years.
In just two years, spending around £77m on transfers, they turned Leicester into the best team in the country, and they lifted the Premier League trophy in 2016.
Vichai Srivaddhanaprabha became a hero for Leicester fans, and the University of Leicester rewarded him with an honorary degree.
He was a quiet man who didn't court publicity and who valued his Buddhist faith - Monks have visited the ground to bless the players.
He's known for his acts of generosity, he has celebrated his birthday by giving fans free beer and cupcakes.
