Bad cop cheats the ax again

She’s the “Teflon Cop.”

A Bronx police officer who falsely accused her boyfriend of abducting and raping her — and a few years later pleaded guilty to using excessive force by pepper-spraying and kicking a suspect — should still be allowed to keep her badge, an NYPD trial commissioner ruled last week.

In 2005, Alfonsina Delacruz lied to New Jersey investigators when she told them that her abusive boyfriend had kidnapped her, driven her to a Bergen County hotel and raped her.

New Jersey authorities stopped short of filing charges against Delacruz because they believed she had been beaten.

NYPD Chief of Personnel Rafael Pineiro called for her termination, but NYPD Trials Commissioner Martin Karopkin and top cop Ray Kelly let her keep her job.

Then, last year, Delacruz and three other officers brutalized a 19-year-old narcotics suspect in a videotaped attack that landed on YouTube. She pleaded guilty Tuesday to three departmental charges, including excessive force and assault.

But Karopkin last week endorsed a negotiated plea between her lawyer and NYPD prosecutors that again allows her to keep her job as long as she keeps her nose clean for 12 months. She’ll only lose 40 vacation days and be put on one year’s probation.

“She should have been fired from the force for the [first] case,” said Roger Blank, the former assistant NYPD lawyer who prosecuted her at the time.
