RIO DE JANEIRO: Atletico Paranaense striker Washington, who has resumed playing after two heart operations, scored his 28th goal of the competition on Sunday as his side won 2-1 at Fluminense to go top of the Brazilian championship.
At the other end of the table, a policeman lashed out at Atletico Mineiro goalkeeper Danrlei with his truncheon as the team surrounded the referee following their 1-0 defeat at Goias sent them back into the relegation zone.
Meanwhile, former South American champions Gremio set a club record of six straight defeats as they lost 1-0 at Parana following an injury-time blunder by Paraguayan goalkeeper Ricardo Tavarelli.
Paranaense's win took them two points clear of Santos, who were held 1-1 at Criciuma, after they overcame a poor start in Rio de Janeiro.
Fluminense went ahead through Antonio Carlos before Washington equalised in the 63rd minute and then set up an injury-time winner for Fernandinho.
In between, Fluminense defender Odvan was sent off for a dreadful tackle.
Former Fenerbahce striker Washington, who is diabetic, has made a remarkable comeback this season after twice undergoing surgery for a blocked artery.
Known as Braveheart, he usually celebrates goals by patting his chest.
Santos visited Criciuma without forward Robinho, their top scorer with 21 goals who returned home before the game after his mother was kidnapped at a barbecue on Saturday night.
Police said the kidnappers had still not contacted the family.
Striker Deivid gave Santos a sixth mintue lead but Angela slipped past a static defence to equalise two minutes later.
The drama continued at the bottom where Atletico Mineiro and Gremio both lost in injury-time.
Mineiro players were furious with the referee after Rodrigo Tabata's goal in the fourth minute of injury time left them pointless in Goias.
They are 22nd in the 24-team table, where the bottom four teams go down.
The players surrounded the official to protest, claiming he had denied them a clear penalty.
Riot police rushed to protect the official and television pictures showed one striking Danrlei with his truncheon, leaving the player spread-eagled on the ground.
Danrlei later reported the incident at a police station. Reuters
