Leo Bruka, 27, who lives near the stadium, told The Telegraph he was driving home from work when he saw the helicopter falling.
"I saw the helicopter coming down, it was spinning very quickly.
"In front of me was a police car. Before it fell the police car went straight away towards where it was falling and I followed them.
"We were less than five seconds away. When we went there there was a man who I think was working inside the property of King Power stadium who opened the back gate.
"The helicopter didn't fall in the [fans'] car park. It fell inside the territory of the stadium. The car park is very close. It might be a car park for the staff because it's in the stadium.
"One of the policeman ran straight away to the helicopter and another got out a fire extinguisher. The first policeman was tying to break the glass of the helicopter, the window, then in this moment I saw a women in tears crying out loud because I think the helicopter just missed her, she was about 20 metres away.
"The fire just started and then there was an explosion.The policemen tried to calm down the fire. The police response was very quick. This all happened in less than one minute, then I could hear all the police coming around the stadium. They hadn't left yet after the match.
"A policeman asked me to stop filming because someone was in the helicopter."
