While driving home west of Johannesburg, Fleurs encountered carjackers who demanded his car keys.
In a tragic turn of events, Fleurs is said to have been shot dead after refusing to comply.
South African Police spokesperson Lieutenant Colonel Mavela Masondo said authorities were awaiting information from crime scene investigators and would make further comment when they had it.
"The police are currently awaiting information on the incident," Masondo said.
"We will comment further on the matter as soon as we get the details."
Fleurs, 24, joined Kaizer Chiefs in October 2023 after a spell at SuperSport United. He signed a two-year deal with an option to extend.
Chiefs, who signed him on a free transfer in October last year, have confirmed the news of his death.
Great sadness
"It is with great sadness that we announce that Kaizer Chiefs player Luke Fleurs tragically lost his life last night during a hijacking incident in Johannesburg," Kaizer Chiefs said in a statement.
"Our thoughts and prayers are with his family and friends at this difficult time."
