Six female city Corrections officers have been indicted on felony charges involving visitor searches, The Post has learned.

The half-dozen suspects, including a captain, are expected to turn themselves in to authorities Monday, sources said.

The officers are accused of filing false reports involving visitors at the Manhattan Detention Complex, known as The Tombs, police sources said.

According to sources, the COs reported not having searched female visitors when they actually had.

The officers are expected to turn themselves in to Manhattan Criminal Court, when the indictment against them will be unsealed.

They face felony and misdemeanor charges, including falsifying records, sources said.

A spokeswoman for the Manhattan District Attorney’s Office declined to comment Sunday.

“We aren’t able to provide any information before a defendant’s arraignment [or the] charging documents are unsealed,” she said.
