A pair of separate Brooklyn fires on Wednesday morning left three people injured, FDNY sources said. Fire Department personnel removed civilians from the second floor of a home on the 2000 block of 57th Street in Mapleton just after 8:30 a.m. on Dec. 6. Paramedics rushed the victims to a local hospital in critical condition and stable condition. Although the cause of the fire remains under investigation, radio reports indicated that members of Hazmat Company 1, Squad Company 1 and the Hazmat Battalion were called in to remove an e-bike and e-battery from the scene.
