Another bad driver story?

Serbian interior minister Dragan Jočić is announcing that last night's attack on Boris Tadić was an unintentional incident, according to B92. In this version, the driver of the car, a domestic employee of the US Embassy in Belgrade, has voluntarily appeared to the police and denied that there was an attack, reporting it as a simple automobile accident.

The story does not sound especially believable. On a not particularly crowded road, a car approaches close several times (at least four, it seems) to a colony containing Tadić's car and several police vehicles with flashing lights and sirens, then bumps and runs off? So the crash is the result of inattention? Some driver who does not like to be told by police to move over? I'm not convinced, are you?
