Concord — A 31-year-old Lebanon man has pleaded guilty in federal court to failing to register as a sex offender.

Paul Dwayne Allen was convicted of felonious sexual assault in Grafton County in 2008, according to a news release.

Allen had been on the registry for several years before moving to Florida in 2015, where he continued to register.

When he returned to New Hampshire around July 2017, he failed to notify authorities and re-register in the Granite State, the release said.

Allen, who is supposed to register under the federal Sex Offender and Registration Notification Act, will be sentenced for the offense on Dec. 19.
