On Jan. 15, Martin County Sheriff William Snyder announced that Deputy Steven O’Leary had been fired, according to The Blast. O’Leary, who had been working with the Martin County Sheriff’s Office for 11 months before his dismissal, was terminated after field tests determined that three of his recent narcotics arrests did not test positive for narcotics, reported local NBC affiliate WPTV. According to video footage from a press conference, Synder said that nine inmates have already been released from custody, and all of O’Leary’s arrests are now under review. In response to the news, the Real Housewives of New York City star, 53, exclusively tells PEOPLE, “We are looking into the allegations of misconduct by Officer O’Leary and we’ll be acting accordingly.” Lars Niki/Getty Luann de Lesseps Says She’s ‘Not Proud of’ Her Arrest: ‘It Was a Really Bad Night for Me’ On Dec. 24, de Lesseps, 53, was arrested in the early morning hours and released on her own recognizance that same day after allegedly attacking a police officer in Palm Beach. She was charged with and originally pleaded not guilty to disorderly intoxication, battery of an officer/firefighter/EMT, resisting arrest with violence and threatening a public servant, according to the Palm Beach County Sheriff’s Office. (She reiterated her plea of not guilty and rejected a plea deal in February 2018.) Following her arrest, de Lesseps — who had tied the knot to ex-husband Tom D’Agostino in Palm Beach on Dec. 31, 2016 — released a statement saying, “This was my first time in Palm Beach since my wedding, and being here brought up long-buried emotions. I want to offer my sincere apologies to anyone I might have offended with my behavior.” She added: “I am committed to a transformative and hopeful 2018.” RELATED VIDEO:Luann de Lesseps Says She Relapsed After Her Ex-Husband and Kids Sued Her: ‘I Felt Betrayed’ Last July, the reality star pled guilty to three charges — battery, trespassing and disorderly intoxication — according to court documents obtained by The Blast.
