Authorities say they searched the apartment of LSU starting quarterback Jordan Jefferson in connection with a bar fight last week that injured four people.

Baton Rouge Police Sgt. Don Stone says the warrant was obtained Wednesday and Jefferson was home during the search.

Stone says Jefferson cooperated while his attorney also looked on, but the quarterback wasn't questioned by investigators at the scene.

Investigators left with several bags of evidence, which Stone says could help prove or disprove allegations against Jefferson. Stone says he cannot say what was taken at this time.

Jefferson is one of four LSU players identified by police as people of interest in the investigation, which authorities say could result in arrests on charges as serious as felony second-degree battery.
