Sao Paulo - Brazilian professional surfer Ricardo dos Santos died on Tuesday in the hospital after being shot three times outside his home in the country's south, allegedly by a police officer.
The 24-year-old was attacked Monday morning near the city of Florianopolis, when he went outside to confront an off-duty policeman and the policeman's younger brother in front of his house.
Police, however, collected conflicting reports about whether Dos Santos asked the men to leave when he spotted them doing drugs or whether he was shot while discussing a car they had parked at his property.
Dos Santos underwent four surgeries at the Sao Jose Regional Hospital, before dying on Tuesday afternoon.
"Ricardito, you did not deserve this... Why did this happen to a good person? I don't understand," surfer Gabriel Medina, current World Tour champion and a friend of Dos Santos friend, posted on Instagram.
Florianopolis military police are holding officer Luis Paulo Mota Brentano, 25, for suspicion in the murder.
"He claimed self defence. He said the victim tried to attack him, and he defended himself," Marcelo Arruda, who is leading the case, told G1 Globo news portal.
The officer, who was on vacation, said Dos Santos threatened him with a knife, although Arruda said that police at the scene found no knife.
The case is being investigated by military and civilian police, who are awaiting autopsy results to help reconstruct the incident.
Dos Santos, a Qualifying Series surfer, had participated in numerous international competitions, where surfers vie for a place in the World Tour.
