A woman was fatally struck by an unmarked police van on a Brooklyn street Wednesday evening, authorities said. Police responded to a 911 call around 6:10 p.m.near Riverdale Ave. and Pennsylvania Ave. in East New York, where cops found a woman with injuries to the head. The woman, who is believed to have been homeless, was lying in the street when she was hit by a NYPD warrant squad vehicle — a black Toyota Sienna — traveling northbound on Pennsylvania Ave., sources and cops said. A plastic basket of clothing and paper bag of goods were left on the west side of Pennsylvania Ave. Kerry Burke/New York Daily NewsThe scene where an unmarked warrant squad van fatally struck a woman lying on Pennsylvania Ave. and Riverdale Ave. in Brooklyn on Nov. 20, 2024.
