BROOKLYN - Police made another arrest Wednesday in the fatal shooting of a livery cab driver, who was killed while trying to stop a robbery in Sheepshead Bay.

Authorities say 21-year-old Widly Viau was taken into custody and charged with murder, robbery and weapon possession in the shooting death of Zalmai Anwari.

Police say Anwari was shot in the head last week after he attempted to prevent the robbers of a cell phone store from fleeing the scene until police arrived.

A second suspect in Anwari?s killing, Donald Michael, was already arrested and charged with murder.
