A former Brooklyn cop — accused of taking sex workers back and forth from appointments, often right after his NYPD shifts — has had his bond revoked and is back in jail.

Eduardo Cornejo, 34, faces interstate prostitution charges and was out on a $200,000 bail bond.

In an August 10th letter addressed to Judge Brian Cogan, prosecutors pointed to a trifecta of evidence that there’s probable cause that Cornejo “has continued to commit prostitution-related offenses while on pretrial supervision.”

Part of that evidence is an Instagram post that shows a photo of Cornejo and a comment underneath.

"His boldness is also on display in the attached Instagram post from July in which the defendant flouts his supervision and brags that ‘I got a bag for the lawyers, like… What's your charges?’…Hop out of the courtroom like #WhatCharges? Big P[IMP]in' on you court steps," Assistant U.S. Attorneys Kevin Trowel and Alexander Solomon wrote.

However, the Daily News reported that attorney Michael Padden said the caption is lyrics rapped by Jay Z in DJ Khaled’s song "I Got The Keys."

According to prosecutors, Cornejo agreed to post an advertisement for prostitution services, and sent texts like "Send me your account info & pics," and this follow-up text — "Yo did it get any better?" — to see if the ad had generated business.

GPS tracking showed Cornejo in the vicinity of five different hotels in Staten Island, East Elmhurst and Woodbury on 10 different dates. One of the locations, according to the prosecutors, is where he "was surveilled pre-indictment conducting prostitution activity."

"There is therefore no legitimate reason for the defendant to have been at area hotels on the 10 listed occasions, other than to promote or patronize prostitutes in violation of the laws of New York," according to the letter.

NYPD Internal Affairs Division also observed him in a car with a prostitute with whom Cornejo had associated prior to his arrest, according to prosecutors.

The NYPD fired Cornejo in January due to failing a random drug test. He also had a history of brutality complaints, and was named in four federal civil rights lawsuits that accused him of false arrest, baseless strip searches, and beatings.
