LONDON, Oct. 28 (Xinhua) -- English Premier League club Leicester City confirmed on Sunday night that their Thai Chairman Vichai Srivaddhanaprabha, along with other four people, had been killed in a helicopter crash.

"It is with the deepest regret and a collective broken heart that we confirm our Chairman, Vichai Srivaddhanaprabha, was among those to have tragically lost their lives on Saturday evening when a helicopter carrying him and four other people crashed outside King Power Stadium. None of the five people on-board survived," the club announced in a statement.

"The primary thoughts of everyone at the club are with the Srivaddhanaprabha family and the families of all those on-board at this time of unspeakable loss," it said. "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."

According to the statement, a book of condolence, which will be shared with the Srivaddhanaprabha family, will be opened at King Power Stadium from 8 a.m. on Tuesday for supporters wishing to pay their respects.
