Vladimir Guerrero has surrendered to police after authorities contend he attacked a police officer in a disco. Guerrero denied being part of an attack. A spokesman for the police in the Dominican Republic maintained that Guerrero "physically attacked" police officer Renato Pena Rojas after a brawl broke out in the disco. Authorities asked Guerrero turn himself in "so the case can be put in the hands of the justice system." "At no time did I attack anyone, nor was I fleeing," Guerrero said. "I presented myself at the jail last night after the complaint from the disco, and this morning first thing I went to the police that are handling the case."
