FBI agents hit the Bronx home of a top aide to Mayor Eric Adams Thursday morning, a law enforcement source confirmed to The Post.

Agents were spotted at the Pelham Bay home of Winnie Greco, who is already under probe by the city Department of Investigation over allegations she improperly used her government position to get perks.

It wasn’t immediately clear if Thursday’s law enforcement action, first reported by News 12 Bronx, was connected to that investigation.

The source also could not immediately say whether a search warrant had been executed.
