Dozens of New York City Housing Authority employees were hauled away in handcuffs as part of a large-scale raid Tuesday morning, The Post has learned.

More than 50 employees were expected to be arrested in connection to the probe, which involved the city Department of Investigation and Homeland Security Investigations, sources briefed on the matter told The Post.

Photos from the scene showed a handful of officers in HSI vests surrounding a car.

The Southern District of New York is expected to provide more details this afternoon.

Calls to both the DOI and the HSI were unanswered Tuesday morning.
