A World Cup security guard has died following a serious fall at Lusail Stadium during last Friday's quarter-final between Argentina and the Netherlands.

John Njau Kibue received emergency treatment inside the ground and was taken to a nearby hospital, where he passed away in intensive care on Tuesday.

The Qatar Supreme Committee confirmed Kibue's passing in a statement on Wednesday and announced an investigation will be held into the circumstances leading to his death.

"We send our sincere condolences to his family, colleagues and friends during this difficult time," the statement read.

"Organisers are investigating the circumstances leading to the fall as a matter of urgency and will provide further information pending the outcome of the investigation. 

"We will also ensure that his family receive all outstanding dues and monies owed."

Kibue is the second known migrant worker to have died since the tournament began, following the death of a Filipino man in the group stage at a resort used by Saudi Arabia.

Speaking last week, Qatar 2022 chief executive Nasser Al Khater said "death is a natural part of life" when he was questioned over the passing of the migrant worker.

The Lusail Stadium is to host Sunday's final between Argentina and either France or Morocco, who face off in the second semi-final on Wednesday.
