Cops are looking for a 41-year-old man with a slight link to Lehman College who sent administrators at the Bronx school a haunting email that threatened New York City Sheriff Anthony Miranda, police said Saturday. Detectives released an image of Dimitry Rappoport and are asking for the public’s help in locating him. Rappoport is accused of sending an email to Lehman College officials that threatened to harm Miranda, a police source said. More precise details of the threat’s content were not immediately disclosed. Lehman College administrators received the email on Oct. 29, cops said. It was one of several emails Rappoport had sent to the college since attending a few seminars there a year earlier. Mayor Adams tapped Miranda to take over the city sheriff’s office in May 2022. Before becoming city sheriff, Miranda was an NYPD sergeant, director of security for the city’s Administration for Children’s Services and longtime head of the National Latino Officers Association. queens borough president bpNew York City Sheriff Anthony Miranda. (Angus Mordant for New York Daily News) Miranda’s deputy sheriffs are the tip of the spear in the city’s ongoing fight against illegal cannabis shops. The city Department of Investigation is looking into whether the sheriff’s office has been improperly seizing cash from the unlicensed pot shops it has raided during Operation Padlock to Protect, a major crackdown on the illegal shops that the sheriff’s office is conducting with the NYPD. Miranda said he had been told of the threat and was taking precautions. “We are working with the NYPD and the sheriff’s office to address any safety concerns for myself and my family,” Miranda told the Daily News on Saturday. “Every threat has to be taken seriously and evaluated for an appropriate response. “The work of the sheriff’s office will continue to move forward,” he said. An email requesting comment from City Hall and the city Finance Department, which oversees city sheriffs, was not immediately returned Saturday. Cops are asking anyone with information that could help lead to Rappoport’s arrest to call Crime Stoppers at (800) 577-TIPS. All calls will be kept confidential.
