The New York City Police Department is stepping up its overnight patrols in parts of Brooklyn and the Bronx.
The department is increasing its police presence because of a recent spike in deadly street violence in the two boroughs.
The number of officers on the street from 10 p.m. to 6 a.m. in 23 precincts could double or even triple.
Police believe high-visibility patrols could deter violence and catch criminals shortly after they act.
