The owner of Leicester City FC died when his helicopter crashed outside the stadium, the club has confirmed.
Vichai Srivaddhanaprabha, two members of his staff, the pilot and a passenger were killed when the aircraft crashed at about 8:30pm on Saturday.
Witnesses said the helicopter just cleared the King Power Stadium before it spiralled out of control and crashed in a fireball.
Thousands of bouquets and scarves have already been left outside the ground.
Mr Vichai, 60, who was married and had four children, bought Leicester City for £39m in 2010.
Under his ownership the club won the Premier League in 2016, having started the season as 5,000/1 outsiders.
Worth an estimated $3.8bn (£2.9bn), Srivaddhanaprabha was chairman of duty-free company King Power International Group.
He bought Leicester in 2010 for £39m, cleared their debts and saw the club win promotion to the top flight four years later. They then beat odds of 5000-1 to claim the Premier League title in 2015-16 in one of the greatest sporting stories of all time.
But the fourth-richest man in Thailand was notoriously private and very rarely gave interviews.
In a statement, Leicester City said the club’s thoughts were with “the Srivaddhanaprabha family and the families of all those on-board at this time of unspeakable loss”.
The club described Mr Vichai as “a man of kindness, of generosity and a man whose life was defined by the love he devoted to his family and those he so successfully led”.
“Leicester City was a family under his leadership. It is as a family that we will grieve his passing and maintain the pursuit of a vision for the club that is now his legacy,” it added.
A book of condolence will be opened at King Power Stadium from Tuesday morning. The team’s next fixture against Southampton in the EFL Cup, scheduled for Tuesday evening, has been postponed.
