Caban was expected to submit a letter of resignation Thursday, to be effective Friday, sources said.
It was not immediately clear who would replace the head of the nation’s largest police force, overseeing more than 33,500 officers and 16,000 civilian employees.
“The news around recent developments has created a distraction for our department, and I am unwilling to let my attention be on anything other than our important work, or the safety of the men and women of the NYPD,” Caban said in an internal email sent to members of service, and obtained by The Post.
“I hold immense respect and gratitude for the brave officers who serve this department, and the NYPD deserves someone who can solely focus on protecting and serving New York City, which is why – for the good of this city and this department – I have made the difficult decision to resign as Police Commissioner,” he wrote.
“Thank you for the trust you have placed in me, and for the opportunity you have given me to serve alongside the members of this great department. I feel strongly that we have the best police force in the world, and have complete faith in the leaders across the NYPD.”
Caban, an NYPD vet of more than 30 years, will leave the top job more than a year after he was handpicked by Mayor Eric Adams.
The police leader quickly faced calls for his resignation from local politicians after federal agents targeted his home and those of other top police officials and aides of Adams in a series of raids Sept. 4, law-enforcement sources previously said.
It’s not clear exactly what the federal agents were looking for, but sources said the probe centers around sweeping corruption and influence peddling.
Caban, whose electronic devices were seized in the raid, has not been charged or accused of wrongdoing.
Rumblings of Caban’s imminent departure, whether by resignation or termination, reached a fever pitch in the days after the feds exited his Rockland County home.
But the mayor shot down the resignation rumors as recently as Tuesday, albeit by largely denying there has been pressure from City Hall for Caban’s ouster.
Caban was appointed to the top job in July 2023 after serving as the NYPD’s first deputy commissioner since 2022. He initially began his career as a cop in 1991, patrolling the streets of the South Bronx.
Caban made history as the city’s first Hispanic police commissioner, but often kept out of the spotlight during his tenure in favor of letting brash subordinates such as Chief of Patrol John Chell grab attention and seemingly steer the department.

Police sources said Caban’s twin brother, James Caban, is being eyed by the feds for his alleged work as a “fixer” for ritzy Manhattan restaurants and nightclubs as part of his “consulting” work.
James Caban, an ex-cop who has also not been accused of wrongdoing, left the NYPD in January 2001 following a slew of complaints and allegations, online records show.
NYPD Chief of Staff Raul Pintos and two precinct commanders in Manhattan and Queens have also been asked to turn over their phones in an investigation sources say travels all the way down to rank-and-file street cops.
Among those ensnared by the federal dragnet were also Adams advisor Timothy Pearson, Deputy Mayor for Public Safety Phil Banks, Schools Chancellor David Banks and their brother Terence Banks and First Deputy Mayor Sheena Wright, sources have said.
The raids and probes rattled police brass, who took to meeting in parking lots away from the feds presumed prying eyes and ears, according to the sources.
The commissioner himself retreated further from public view after feds seized his electronic devices, even opting to no-show the annual 9/11 memorial ceremony this week — an unheard-of move for the city’s top cop.
