THE number of NYPD cops using drugs, stealing property – even from the dead – and committing other acts of corruption, including extorting sex from female suspects, spiked sharply last year, according to a confidential NYPD report.

The astonishing wrongdoing in cluded everything from cops solicit ing sex in exchange for overlooking crimes to stealing credit cards from the homes of dead people to hiring a hit man to commit murder.

The tawdry tales include stories of cops not only betraying their badges, but also their brother and sister officers in blue.

In one case, two cops allegedly disclosed the identity of an undercover officer who came into a restaurant while they were bartering for sex with a woman they had once arrested.

In another case, two Manhattan cops were caught looting money from a precinct house’s kitty that included cash collected from T-shirt sales for the cancer-stricken daughter of yet another cop.

“It was ugly,” a source said.

In yet another incident, a cop teamed up with a “police impersonation” robbery ring after she could not find another corrupt cop to work with the gang.

And then there was an officer who hung out with drug dealers who also made “friendly” bets on sports events – with the payoff in marijuana.

The revelations contained in the NYPD’s Internal Affairs Bureau 2006 Annual Report – obtained by The Post – include:

* Arrests of New York’s Finest rose 25 percent in 2006 over the previous year, from 91 to 114.

* The number of cops caught using drugs last year jumped 138 percent, from eight incidents the previous year to 19, including one cop using PCP (phencyclidine), and another shooting steroids into his butt.

* Fraud allegations involving insurance, credit card and welfare swindles rose 85 percent to 50 complaints from 27 the previous year.

* The number of cops stripped of their guns and badges and placed on modified duty jumped 55 percent, from 137 to 212, but suspensions fell 11 percent from 159 to 142.

The Post pieced together the accounts using sources, court records and district attorneys’ offices, along with the tightly guarded annual IAB study.

For its part, the NYPD insisted The Post submit in writing its requests for specific case information and names of fired or disciplined cops, which the newspaper did on Aug. 14.

Since then, follow-up reminders, in person and via e-mail, have fallen on deaf ears.

The IAB states that cops accused of stealing property made up 34 percent of the 1,057 corruption cases launched last year – with 357 thefts reported, an 8.5 percent jump over the previous year’s 329 cases.

Among them were two cops at a Manhattan precinct who handled thousands of dollars collected from T-shirt sales and vending-machine proceeds for their stationhouse “club.”

Investigators determined the duo skimmed about $4,000 from the club’s bank account, purchasing tires for their cars, paying Internet hookup fees and cellphone bills.

Adding insult to injury, the sources said, some of the stolen cash was raised to defray medical costs incurred by the cancer-stricken daughter of an NYPD sergeant.

The duo was convicted of grand larceny at a departmental trial and fired. The DA declined to prosecute, primarily because bank records had been destroyed, sources said.

There’s also Mammianne Zadja, who reportedly tried to steal from her own family, changing the deed to her father’s home and removing her brother’s name from it.

The 32-year-old initially obtained power of attorney for her healthy father by filing phony medical papers showing he had Alzheimer’s, court papers alleged.

She then axed her brother from the deed and applied for a second mortgage on the house.

The cop was caught after a bank loan officer became suspicious when he held a conference call with Zadja and her “father,” who turned out to be someone posing as her dad.

She was fired, but at the family’s request, the Staten Island DA did not press charges.

Perhaps the most ghoulish thievery involved Officer Eduardo Saillant, 38, of the 60th Precinct, who swiped credit cards from the homes of four dead people last year.

Saillant was accused of responding to 911 calls involving people who died of natural causes and taking their cards and using them at Home Depot hardware stores in New York and New Jersey and to buy gasoline for his car.

Saillant, a divorced father of two, resigned from the NYPD. His criminal case is pending, according to Brooklyn DA Joe Hynes.

The most notorious crime involved the widely reported conviction of police recruit Kabeer Din, 22 who tried to hire a hit man for $3,000 to assassinate his Suffolk, L.I., girlfriend.

But the worst betrayal might involve cops allegedly in the process of extorting sex from a woman.

Two officers came under investigation after a woman arrested in a drug roundup claimed they offered her drugs for sex.

IAB zeroed in on the cops, listening in on a call in which one cop was heard offering marijuana for sexual favors. The cop, his partner and the woman then met in a popular Manhattan eatery, El Malacon on Broadway and 175th Street, where the officers bragged about their coziness with drugs.

The rendezvous became even more untoward when an undercover cop walked in and one cop quickly gave up his identity, “warning her to be careful since he works in the area,” according to the report.

The officer who ratted out the undercover resigned the force. The other cop was suspended, but remains a cop.

In The Bronx, a veteran NYPD detective was found guilty of getting a woman who was implicated in an identity-theft case to perform oral sex on him.

Detective Dominic Calvanico initially insisted the woman sign a confession and cooperate, according to the report.

He then told her that if she would “take care of him” – engage in sexual activity – he would “talk to the DA and make the case go away,” according to the report.

“Fearful of being arrested and having just started a new job [at a hospital], the victim met the detective in her car, where she performed oral sex on him,” the report says.

She spit his sperm into a tissue, which was thrown into the center console. Afterward, she alerted Internal Affairs and the Bronx DA.

IAB later retrieved the detective’s investigative case folder, where they found the woman’s written confession, but no mention of it in the file.

The detective, who claimed the sex was consensual, was found guilty at his NYPD trial of bribe receiving, coercion, associating with a criminal and filing false statements.

In an extraordinary plea deal worked out among the NYPD, the DA’s office and his union, Calvanico – a cop for 19 years and 11 months – agreed to resign and surrender a portion of his pension to avoid criminal charges.
