The father of Michael Brown, the black
American whose killing by
police triggered countrywide
protests, on Friday marked the fifth anniversary of his son's death by calling on the
Justice Department to re-open its investigation into the shooting.
Prosecutors dropped the case against the officer who shot the unarmed 18-year-old, sparking riots in Ferguson, a suburb of St Louis in the conservative state of Missouri.
"I am demanding evidence to be reanalyzed, and accountability to follow," Michael Brown Senior told a news conference.
