A former detective with the New York City Police Department (NYPD), Matthew Lambert, has admitted to misconduct following a series of inappropriate actions while on duty. Lambert, 33, pleaded guilty to three counts of official misconduct and one count of receiving unlawful gratuities, as confirmed by the Manhattan District Attorney’s Office in a press release.

The charges stemmed from Lambert’s engagement in sexual activity with a woman whom he had recently arrested and sending flirtatious messages to two other crime victims whose cases he was investigating. His guilty plea has resulted in a sentence of two years of probation, during which he is also required to attend counselling and complete 100 hours of community service.
Manhattan District Attorney Alvin Bragg expressed condemnation for Lambert’s conduct, stating, “The defendant’s disturbing conduct is unacceptable for a member of law enforcement.” He highlighted the double jeopardy of Lambert misusing his authority in sensitive situations while further complicating the already challenging experiences of victims.
Lambert began his career with the NYPD in 2014 and progressed to the rank of detective in 2022. His troubles began during a case in March 2024, when he was assigned to investigate a missing package. Throughout the subsequent months, Lambert used his police phone to contact the woman who reported the theft. He sent her a series of inappropriate messages, including one that inquired if others had commented on how youthful she looked, and another suggesting a celebratory drink once her case was resolved. After receiving these messages, the woman eventually blocked Lambert’s number.
In addition to the package theft case, Lambert was involved in investigating an assault that same month. During this case, he also sent disturbing messages to the victim, stating, “You are absolutely beautiful,” which he attempted to qualify as respectful by adding he meant no disrespect to her existing relationship.
The misconduct did not end there. In May 2024, Lambert arrested a woman for petit larceny and used his position to manipulate her situation. He informed her that he could issue a desk appearance ticket, avoiding the need to take her into central booking. However, in an alarming turn, Lambert proceeded to share an explicit image with her, stating, “If you want I could come say hello. Up to you. You tell me if you want me to.”
Lambert then allegedly drove to her residence, where they had sexual relations in his car. Following the encounter, he texted the woman, saying, “You’re so cool. Thanks for hanging out,” highlighting a blatant disregard for professional boundaries.
As a direct result of this plea deal, Lambert has forfeited his right to return to law enforcement in New York State—a significant consequence of his actions. He resigned from the NYPD in 2025, prior to reaching his plea agreement.
This case reveals troubling dimensions of abuse of power within law enforcement, where individuals in positions of authority exploit their status to take liberties with those they are meant to protect. The repercussions of such misconduct extend far beyond the immediate individuals involved, potentially eroding public trust in police institutions.
The Manhattan District Attorney’s Office continues to assert that such behaviour within their ranks is intolerable, and efforts will remain steadfast in holding officers accountable for malpractice. Lambert’s conviction serves as a cautionary tale about the ethical responsibilities incumbent upon law enforcement members in their duty to serve and protect the community.
