The helicopter owned by Srivaddhanaprabha crashed outside the club's football stadium, following their Premier League game against West Ham.
It happened in the King Power Stadium car park just after 8.30pm on Saturday.
Police cars and emergency services rushed towards the area where flames were clearly visible before the area was evacuated.
Leicestershire Police said it is dealing with an incident at the stadium "after an aircraft came down in a car park behind the ground."
A spokesperson for Leicester City Football Club said: "We are assisting Leicestershire Police and the emergency services in dealing with a major incident at King Power Stadium. The Club will issue a more detailed statement once further information has been established."
First moments after the helicopter crash
Srivaddhanaprabha owns the King Power company, bought Leicester City in 2010 and became chairman the following February.
After the club overcame the odds and won the Premier League in 2016, the Thai owner became adored by fans.
He normally leaves the stadium by his helicopter, which lands in the centre circle on the pitch, after every Leicester home game.
One witness, who wished not to be named, but has had a season ticket for over 40 years, said: "I saw [Leicester City goalkeeper] Kasper Schmeichel run out first and then loads of security guards and stewards.
"I was stood outside the ground but it crashed on the other side."
