Longtime city detective James Byrne leaves NYPD to join US Secret Service

Long-time NYPD Det. James Byrne — who served as a trusted advisor to the department’s top cop — is leaving the ranks of the Finest to join the US Secret Service, The Post has learned.

Byrne, a senior communications advisor and detective first grade, “has served the NYPD and the people of New York City with distinction for more than two decades,” Commissioner Edward A. Caban said in a statement.

“Throughout his career, James has been a trusted communications advisor to many in the executive ranks, as well as a steady and reliable liaison to members of the press,” the commissioner said. “During my tenure, James led my Executive Communications Team and served as chief speechwriter.”

A nearly 23-year-veteran, Byrne has also served in the office of the first deputy commissioner, the deputy commissioner of public information — handling dealings with the media — as well as the chief of department and the community affairs bureau.

“An integral member of my staff, he will be missed greatly,” Caban added. “On behalf of the entire NYPD, I wish him all the best in his new role with the United States Secret Service.”

Byrne began his service with the NYPD in July of 2001, patrolling Bedford-Stuyvesant’s 81st Precinct, mostly on the overnight shift, according to his LinkedIn page.

Two months into his tenure, he was a first responder at Ground Zero in the wake of the tragic Sept. 11 terror attacks, he wrote.

Just five months ago, he reached a personal milestone — seeing the Macy’s Thanksgiving Day parade in person for the first time, surrounded by his wife and young sons.

“Also great to see so many from the work family, too,” he posted. “Thank you to all of the first responders who were out there making sure it was a safe day for all. Grateful for many blessings in 2023.”
