KEARNEY, Neb. (AP) — A Nebraska man has been indicted on five federal counts, accused of having sex with probationers while he was a probation officer in Kearney, then lying to the FBI about it.

A federal grand jury handed down the indictment Wednesday against 56-year-old Thomas Peterson. In it, Peterson is charged with four counts of deprivation of civil rights under color of law and one count of making false statements to a government agent.

The indictment says that from 2010 through 2014, Peterson had sex with four different women while they were on probation and while he was serving as their probation officer. The indictment also accuses Peterson of tipping off probationers to planned drug tests and of threatening to have one woman’s probation revoked unless she left the state.
