Cops were warned to be watchful, especially in Brownsville's Howard Houses.

Cops were warned on Friday that a Brooklyn street gang may be gunning for them soon, according to authorities.

Detectives from Brownsville’s 73rd Precinct received information that the gang, known as the Young Gunnerz, have made “threats of violence” against cops, according to the internal memo, acquired by the Daily News on Friday.

Cops citywide were told to be careful, especially in Brownsville and the Howard Houses where the gang is active.

“All (officers) on patrol are to use caution and to be aware of their surroundings at all times,” the memo noted. Earlier this week, cops were told members of the Latin Kings had planned to shoot cops in the Bronx, but the threat was ultimately deemed not credible.
