New York Police Department Commissioner Edward Caban is stepping down Thursday, multiple sources with knowledge of the decision tell CNN, marking the first high-profile departure from Mayor Eric Adams’ administration since the start of four separate federal investigations into his office and the NYPD.

New York City Police Commissioner Edward Caban resigned Thursday, one week after it emerged that his phone was seized as part of a federal investigation that touched several members of Mayor Eric Adams’ inner circle.
