A 39-year old Buffalo woman was in critical condition Sunday in Erie County Medical Center following a crash Saturday on the city’s East Side, police reported.

Accident investigators said a work van may have run a red light at Fillmore Avenue and Clinton Street around 5:45 p.m. and hit the woman’s grey Chevrolet minivan sending it into a traffic signal pole while the work van crashed into an unoccupied building.

Police spokesman Michael DeGeorge said an investigation into the crash was continuing and no charges have been filed.
