As many as 100 raucous cops turned up at midnight at the Bronx DA’s Office, screaming their support for 15 fellow officers who were scheduled to surrender in the NYPD ticket-fixing scandal.

A 16th cop was arrested earlier last night.

By 1:30 a.m. today, all had turned themselves in.

Their brother officers loudly applauded them as they walked into the building. They also jeered Internal Affairs detectives, whose investigation led to the indictments.

“You p—–s,’’ shouted one cop at the IAB contingent.

One cop, José Ramos, was arrested at around 8 p.m. last night at his Washington Heights home, said his lawyer, John Sandleitner.

Ramos’ wife, Wanda Abreu, was also taken into custody.

The charges against them weren’t immediately clear.

Thirteen cops, one lieutenant and two sergeants face possible charges including obstruction, official misconduct, perjury and bribery.

“They’re anxious to get in there and prove their innocence,” one source said.

Prosecutors are expected to unseal indictments, totaling about 1,000 pages with nearly 1,500 criminal counts, against the officers and five civilians today at an arraignment before Criminal Court Judge Steven Barrett, a source said.

The DA’s Office released a statement to The Associated Press, stating that the indictments will include “allegations of police corruption covering a broad spectrum of crimes.”

The cops were indicted on Sept. 23, and had been nervously cooling their heels since, waiting for the DA to take action.

Lawyers for the officers were notified starting at around 2:30 p.m. yesterday of the impending arrests, prompting them to hastily arrange for their clients’ surrender, the source said.

At least one also may face charges of profiting from drug sales as well as taking electronics in exchange for fixing traffic and parking tickets.

Of the rank-and-file cops, three are union trustees and six are union delegates, law enforcement sources said.

On wiretaps already played for a grand jury, at least some of the officers reportedly are heard discussing fixing tickets for family, friends and even a Yankee executive — and also making DWI and reported domestic dispute incidents disappear.

Sources said the cops to be charged with misdemeanors are expected to be released without bail. Those charged with felonies will have to post bail.

One of the cops involved is 40th Precinct Sgt. Jacob Solorzano, a source confirmed.

Ramos, who was Solorzano’s NYPD officer driver, sparked the probe back in 2009 when—already under investigation for alleged ties to a drug dealer — he was heard on a wiretap talking to a friend about fixing a ticket.

The highest ranking cop under investigation is Lt. Jennara Everleth Cobb of Internal Affairs. She is accused of leaking information about the probe to Bronx cops.

A source said the indictment of Sgt. Marc Manara had been surprising since there had been little previous indication that he was involved.

Other prominent names caught up in the probe include PBA trustees Brian McGuckin, Michael Hernandez and Joseph Anthony.

The other cops were identified by sources as Virgilio Bencosme, Christopher Scott, Luis Rodriguez, Christopher Manzi, Eugene O’Reilly, Jaime Payan, Jeffrey Regan, Ruben Peralta and Jason Cenizal.
