New York Police Commissioner Edward Caban is resigning, he and his lawyers confirmed.

The resignation was also sent in a letter from Caban’s lawyer to the town hall. The resignation takes effect on Friday.

His resignation comes amid a federal investigation into possible corruption in New York City government, during which authorities seized cellphones from Caban and other NYPD officers last week, according to sources familiar with the investigation.

Caban’s lawyers, Russell Capone and Rebekah Donaleski, said in a statement that they had been informed that Caban was “not the subject of any investigation by the Southern District of New York” and that he “expects to fully cooperate with the government.”

Caban also said he would “continue to fully cooperate with the ongoing investigation.”

“My full focus must be on the NYPD – the department I deeply admire and to which I have dedicated my career,” Caban said in a statement. “However, the noise surrounding recent developments has made that impossible and has hindered the important work our city needs. I have therefore decided it is in the best interest of the department that I resign from my position as Commissioner.”

In an email to the NYPD obtained by ABC News, Caban did not directly address the investigation, saying only that he had made the “difficult decision to resign” in light of “recent developments.”

“My full attention has always been on the NYPD – the department and people I love and have dedicated over 30 years of service to. However, news of recent developments has distracted our department, and I am unwilling to focus my attention on anything other than our important work or the safety of the men and women of the NYPD,” he said in the email. “I have tremendous respect and gratitude for the brave officers who serve this department, and the NYPD deserves someone who can focus solely 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 Chief of Police.”

New York Mayor Eric Adams said in a speech Thursday that he had accepted Caban’s resignation and appointed former FBI agent and former director of the New York Department of Homeland Security Tom Donlon as interim commissioner.

“I respect his decision and wish him well,” he said of Caban. “Commissioner Caban has dedicated his life to keeping our city safe and in the 13 of 14 months he has served as commissioner, crime has decreased.”

Federal agents also searched the homes of Vice Mayor Phil Banks, Vice Mayor Sheena Wright and Schools Chancellor David Banks last week, according to sources. Sources said the FBI seized evidence, including electronic devices, during the searches. No charges have been filed.

Federal prosecutors in Manhattan would not disclose details of their investigation, but sources said one focus is on city contracts and a second focus is on enforcing regulations for bars and clubs.

Adams, who held the press conference virtually after testing positive for COVID-19 earlier this week, said in his remarks Thursday that he was “surprised” to learn of the investigation into his administration.

“I take it extremely seriously,” he said. “I spent more than 20 years in law enforcement, and so every member of my administration knows that I expect us to follow the law.”

The mayor’s chief counsel said last week that investigators had given them no indication that the mayor or his staff were the target of any investigation.

Adams also stressed last week that he was not aware of any “misconduct” on the part of anyone in his administration and promised his cooperation in the ongoing investigation.

“As a former member of law enforcement, I say it very clearly over and over again. We follow the rules. We make sure we cooperate and share all the information that is required, and it would just be inappropriate to impede the review while it is taking place,” Adams said in an interview with CBS New York on Sept. 5. “I am not aware of any wrongdoing, and as I said, I will follow the rules and continue to tell the team to do that. And that is what they have done, to my knowledge.”

Several high-ranking NYPD officials, including Caban, received subpoenas to turn over their cellphones on Sept. 5, sources said. The following day, investigators requested the phones of other police officers, including district chiefs in Manhattan, and questioned officers in a building next to police headquarters, sources said.

“The Department is aware of an investigation by the U.S. Attorney’s Office for the Southern District of New York involving members of the armed forces. The Department is cooperating fully with the investigation,” an NYPD spokesman said on September 5, referring further questions to the U.S. Attorney’s Office, which declined to comment.

Caban’s family has ties to nightlife. Richard Caban, Edward Caban’s brother and a former NYPD lieutenant, owned a now-closed Bronx restaurant, Con Sofrito. Edward Caban’s twin brother, James Caban, a former NYPD sergeant, owned a Bronx apartment building that once housed a bar called Twins on the ground floor.

Caban began his career with the NYPD in 1991 as a Bronx police officer. He rose through the ranks and became the NYPD’s first deputy commissioner in 2022.

Adams appointed him commissioner in July 2023 after Keechant Sewell, the city’s first female commissioner, resigned.

After the subpoena became known, City Councilor Robert Holden called on Caban to resign.

“I think he needs to do something because it casts a dark, grim shadow on the police force,” Holden said Sunday on CBS’s “The Point with Marcia Kramer.”

“We have to trust that he will follow the law. He is a role model for the entire department,” Holden said.
