A woman reported to police that a man wearing a mask and carrying a knife raped her in a Finley mobile home park off Highway 397 this week.
The male suspect's head and face were covered with only his eyes exposed when he knocked on her door about 2 a.m. Wednesday, said the Benton County Sheriff's Office.
When she opened it, he forced his way in, assaulted her and left, the sheriff's office reported. The assault occurred at Kelley's Estates Mobile Home Park.
The suspect is described as 5-foot-7 with a thin build and a dark complexion.
Anyone with information about the assault is asked to call the sheriff's office detectives' division at 735-6555. After business hours, call the non-emergency dispatch phone number at 628-0333.
