July 23 (UPI) -- A man allegedly armed with a knife was fatally shot by police in the middle of a Madison intersection, authorities said, sparking protests and igniting public anger.

The incident occurred early Wednesday afternoon in Madison's Marquette neighborhood.

Madison Police Chief John Patterson described the deceased during a press conference as a man in his 30s.

He said officers had been called to Marquette at about noon over reports of a man inspecting parked cars.

On arrival, officers attempted to contact the man, who allegedly fled the scene on a bicycle, Patterson said. Officers encountered him again at about 1:30 p.m. at the intersection of Baldwin and Williamson streets, where the man either fell or was removed from the bicycle by police.
