A career con charged with raping a drunken 29-year-old woman in a West Village stairwell — after lying that he was a neighborhood watchman — insisted today that he’ll prove his innocence at trial in October.

Manhattan prosecutors say Ivan Ramos is linked to the Perry Street attack by witness accounts, video surveillance and the victim’s ATM card, on him when he was arrested at the scene.

Ramos has claimed nonetheless that cops have the wrong guy. At a brief court appearance today, prosecutors asked for two more months to provide DNA reports to the defense, explaining that they need to conduct more time-consuming high-sensitivity testing on the samples at hand.

“We are still on track for an October trial,” assistant district attorney Craig Ortner told Manhattan Supreme Court Justice Richard Carruthers.

“I’m convinced that ultimately he’s going to be vindicated by the results of the high-sensitivity DNA testing or, at the latest, by a trial itself,” Ramos’ lawyer, Mel Reiss, said after court.
