Rock Valley, IA (KICD)--Area authorities are looking into another suspicious person report.

The Sioux County Sheriff's Office received a report of a suspicious person near the intersection 305th Street and Fig Avenue, one half mile east of Rock Valley around 7:15 Saturday night.  A pair of 13-year-old girls were walking on Fig avenue when they saw a gray or silver Dodge or Chrysler minivan drive eastbound and then westbound two times on 305th St. The vehicle then stopped at the intersection of 305th Street and Fig Avenue and the male driver asked the girls what their names were.

The girls started walking away and the van left the area.  A short time later they again saw the van coming toward them on Fig Avenue so they ran behind some houses.  The van went past their location twice and then left the area again.

The driver of the van is described as a while male in his 30's or 40's with tan skin; he had short facial hair on his jaw and chin, was wearing a white or light colored baseball cap and was smoking a cigarette.
