WASHINGTON (AP/WCBS 880) — A judge has sentenced a New Jersey man to three years of probation for posing as a U.S. Secret Service agent and entering the U.S. Department of Health and Human Services building when it was closed.

The U.S. attorney’s office says U.S. District Judge Colleen Kollar-Kotelly sentenced 47-year-old Frederick James Nickerson of Hopatcong, N.J., on Tuesday. Nickerson pleaded guilty in May to impersonating a federal officer.

Authorities say Nickerson admitted to flashing credentials claiming that he was a Secret Service agent to a security guard at the HHS headquarters in Washington on Jan. 2. He said he needed to go to Secretary Kathleen Sebelius’ operations center.

Another charge alleging Nickerson impersonated a police officer to enter the D.C. police headquarters in December was dropped as part of his plea deal.
