A registered Nebraska sex offender remains in jail under new charge.

A 28-year-old registered sex offender remains in jail, accused of sexually assaulting a 15-year-old-girl.

A Saline County jail spokesman said Thursday that Jason Pelan of Crete remained in jail on bail of $500,000.

Police arrested Pelan on Friday after receiving a report that he was chasing a 15-year-old girl down a street in Crete.

The girl told police that Pelan had sexually assaulted her. Police say she and Pelan have been communicating for several months. She is from Malcolm.

Pelan was convicted in 2006 of attempted first-degree sexual assault in Butler County.
