ALBANY — Vito Lopez’s prosecutor will limit his probe of the powerful Brooklyn Democratic leader to alleged sexual harassment of young female Assembly aides, The Post has learned.

Staten Island DA Dan Donovan’s office doesn’t have “the resources to do a full-scale forensic investigation of all the other players” with potential involvement in the Lopez scandal, said a source who was told of the probe.

Donovan’s office would not comment.

Called in as a special prosecutor, Donovan is investigating allegations by the state Assembly Ethics Committee that Assemblyman Lopez groped and kissed two staffers.

But the probe does not appear to be looking at the roles others in government may have played in arranging or approving a secret $103,800 settlement in an earlier claim of sex harassment by other Lopez staffers.

The settlement was approved by Assembly Speaker Sheldon Silver (D-Manhattan) and was reviewed by the offices of Attorney General Eric Schneiderman and Comptroller Tom DiNapoli.

Lopez has denied the charges.
