SYRACUSE — A 30-year-old registered sex offender on federal probation was arrested Wednesday for investigation of sexually abusing two 14-year-old girls.

Robert Lloyd Zesiger, of Layton, was arrested by Syracuse police and booked in the Davis County Jail.

Police say Zesiger abused the girls for about two weeks in the Syracuse area before one of the victims told her parents and police were notified.

Syracuse Police Lt. Tracy Jensen said the man came into contact with the girls through his girlfriend, who lives in the area.

Jensen said Zesiger is on federal probation for viewing child pornogray.

Zesiger is being held for investigation of aggravated sexual assault and three counts of forcible sexual abuse.

Police say other girls also may have been victimized. They've asked anyone with information about the case to call 801-825-4400.
