Bill De Blasio to NYPD: Admit Tix-Fix Mess

Public Advocate Bill de Blasio has jumped into the NYPD ticket-fixing controversy, demanding the city’s top cop come clean over allegations that some officers covered up busts for crimes a lot more serious than minor motor-vehicle infractions.

“I am writing to express my deep concern regarding alleged attempts to cover up incidents of domestic violence and driving while intoxicated involving off-duty NYPD officers,” de Blasio wrote in a May 2 letter to Police Commissioner Ray Kelly.

“The participation of any officers in the suppression of these reports would constitute a profound betrayal of the public trust and could rise to the level of a felony.”

Police spokesman Paul Browne was dismissive of de Blasio’s letter yesterday, saying there’s no proof that cops made any felony arrests go away.

Media reports “about domestic violence and other serious offenses [have] never been verified,” Browne said.

But de Blasio said the allegations alone may scare domestic-violence victims from coming forward and compromise the city’s anti-drunken-driving campaign.

“These allegations were simply too serious to be ignored. I sent this letter to the NYPD in the hopes that the department will allay public concerns by giving a full account of its internal investigation,” he said.

He demanded that Kelly investigate both the initial incidents and any allegations that cops made records vanish.

“The offenses involved in these alleged cover-ups would also represent serious threats to the safety of New Yorkers,” he wrote.

“I am deeply troubled by the effect these reports may have on the willingness of domestic-violence victims to seek justice and protection from law enforcement.”

The ticket-fixing probe, by Bronx DA Robert Johnson’s office and the NYPD’s Internal Affairs Bureau, may result in criminal charges for 40 or more cops and department disciplinary action for as many as 500 others.

The scandal extends from cops on patrol to the deputy-inspector level, sources have told The Post.

And while most cases are out of The Bronx, where a grand jury is hearing evidence, they extend to all five boroughs.

Numerous cops have been picked up on wiretaps talking to union reps about fixing traffic tickets for pals and family members, and at least one union official has testified before the panel, the sources said.
