San Diego Chargers linebacker Thomas Keiser was arrested after a fight at a nightclub several hours after the team's victory over the Kansas City Chiefs clinched a spot in the playoffs, police said Monday night. Keiser was taken into custody on suspicion of misdemeanor battery shortly before midnight Sunday when someone asked for a citizen's arrest, San Diego police Capt. Dino Delimitros said. Police had been called to the restaurant and nightclub known as barleymash in the city's Gaslamp Quarter after "some sort of fight," Delimitros said. "He got in a fight with somebody, the bouncers got involved, the police came up and somebody demanded a citizens' arrest," Delimitros said.
