David Nieland, the investigator who led the Department of Homeland Security's probe into the 2012 Secret Service prostitution scandal, has "quietly resigned" after being caught with a prostitute himself, The New York Times reports.
Florida sheriff's deputies caught Nieland "entering and leaving a building they had under surveillance as part of a prostitution investigation," according to the Times. The deputies interviewed one of the prostitutes involved, who identified Nieland's photograph and stated that he had paid her for sex.
In April 2012, eight Secret Service agents on assignment in Colombia were fired when "it became known that they had had prostitutes in their hotel rooms," the Times notes. Nieland was in charge of the inspector general's Miami office at the time, and led an investigation into how the Secret Service handled the incident.
Nieland resigned from the Department of Homeland Security in August, but he denies the allegations. There are two investigations underway, but Nieland has not yet been charged by federal or local governments.
