South Africa's football captain and goalkeeper Senzo Meyiwa was shot dead on Sunday night by three gunmen.
The incident reportedly happened at Meyiwa's girlfriend's house in Vosloorus, south of Johannesburg.
Meyiwa was killed around 8 pm after two gunmen entered the house while an accomplice waited outside, South Africa's national police force said on its Twitter account.
The three assailants then fled on foot, according to the police service, who have offered a reward of nearly $14,000 for information that can help track the assailants.
Police said there were seven people in the house during the attack, and that the shooting followed an "altercation."
Authorities said they would do everything possible to find the killers.
The 27-year-old played for Orlando Pirates and had played in South Africa's last four Africa Cup of Nations qualifiers.
On Saturday, he was in action for his club, which progressed to the semi-finals of the South African League Cup. Orlando Pirates beat Ajax Cape Town 4-1.
The team said on its website: "The Orlando Pirates Football Club family has learned with sadness about the untimely death of our number one goalkeeper and current captain Senzo Meyiwa."
