Police say the arrest of Elvis Dumervil was preceded by a road-rage incident in which the Broncos defensive end and another man lifted their shirts and displayed firearms to people in another vehicle. A police report released Monday says Dumervil was driving his Range Rover in Miami Beach and following a silver Mercedes, in which another man, Andy Aguste, was a passenger. While stuck in traffic Saturday evening, a white Chevy Impala, driven by Kristine Ramirez, merged between the two cars. According to the police report, the parties got into a verbal argument that included horn-blowing and name-calling. At some point during the argument, the accusers in the Impala say, Aguste exited the Mercedes and approached them. Aguste allegedly verbally threatened the riders in the Impala and then lifted up his shirt to reveal a firearm in his waistband, police said. The accusers also say in the report that Dumervil, a Miami native, walked up to the Impala and lifted his shirt to display a firearm, but never said anything.
