Authorities warned cops on both sides of the Hudson River yesterday to be on alert after getting threats from gang members vowing to kill police officers in retaliation for last Saturday's shooting of an unarmed Queens man.
NYPD officers were told of the two threats during roll calls across the five boroughs as investigators in the city and in Essex County, N.J., were trying to confirm the origin and validity of the threats. Neither threat mentioned specific targets.
