The deadly Legionnaires’ outbreak gripping Harlem has city officials in hot water — as locals accused them Friday of dropping the ball on life-saving inspections and needlessly slow-walking revealing exactly where the disease hit.

Announcement of the latest death comes just hours after city officials identified 12 cooling towers in 10 Harlem buildings that tested positive for Legionnaires' disease.

Three people in central Harlem have already died from legionnaires’ disease, according to the NYC Health Department.
