SANTIAGO - Sergio Aguero re-ignited Argentina's Copa America campaign with the only goal in a 1-0 victory over historic rivals Uruguay on Tuesday, as the football tournament was rocked by the arrest of Chile star Arturo Vidal for drink driving after a car crash.
Aguero bagged his second goal of the tournament in the 56th minute of a niggly battle between the 1930 World Cup finalists in their 199th meeting.
The result leaves Argentina firmly on course to win Group B, with only one game against minnows Jamaica, beaten 1-0 by Paraguay in Tuesday's early game, remaining.
But the action on the pitch was overshadowed late on Tuesday by the revelations concerning Chile midfielder Vidal.
The player, who became the top scorer for the tournament on Monday with three goals after bagging a brace in the hosts' 3-3 draw with Mexico, was detained by police after testing positive for alcohol following a late-night crash.
Vidal, who was travelling with his wife when the accident occurred, suffered "minor injuries" but his wife's wounds were described by the police as "moderately serious".
Images on Twitter showed a red Ferrari with the driver's side reduced to a mangled wreck.
"Because he was driving under the influence of alcohol... (Vidal) is being held," the police said.
It was not immediately clear how Vidal's arrest would affect his participation in the tournament.
Chile face Bolivia in their final Group A match tomorrow when they will be attempting to make certain of their place in the last eight.
Earlier on Tuesday, Argentina captain Lionel Messi praised his team-mates for keeping their cool in the hard-fought win over Uruguay.
"It was a tough match from their side. They didn't want to play that much," said Messi, who was subjected to a series of cynical fouls throughout.
"But we showed that we can also play that kind of game if we need to.
"Yet, we tried to keep playing our game and that's how we found the goal through Kun (Aguero)."
The winning goal came on 56 minutes when a cross from Pablo Zabaleta was met by his Manchester City team-mate Aguero who headed in.
Paraguay moved closer to the last eight with the win over Jamaica. A freak goal from Edgar Benitez proved the difference, with the striker unwittingly deflecting a headed clearance by Jamaica goalkeeper Duwayne Kerr into an empty net on 36 minutes.
The win means Paraguay need only a draw with Uruguay to be sure of finishing second in the group.
