Residents said a third person, believed to be another police officer tasked with protecting Feruzi, was seriously injured in the incident.
“We heard around 20 gunshots, everyone fell to the ground, people saw a Toyota car speeding away,” said a neighbour, who did not witness the shooting himself.
Around an hour after the attack police had yet to arrive at the scene, according to the AFP news agency.
Saturday’s assassination will add to tensions in Burundi after a month of protests against President Nkurunziza.
A coup attempt to remove Nkurunziza by army officers opposed to his decision to contest the presidential vote failed after the intervention of loyal members of the military.
More than 20 people have died in anti-government protests since the president’s announcement to stand in late April.
