WASHINGTON COUNTY, Wis. (CBS 58) -- Washington County sheriff's investigators are asking for the public's assistance in locating an alleged dangerous wanted fugitive. 

Authorities say 38-year-old Willie Johnson is wanted for his alleged attack on a female companion that occurred over a several-day period leading up to Christmas. He's wanted for mayhem, aggravated battery causing great bodily harm, strangulation, false imprisonment and criminal damage to property, all with the use of a dangerous weapon as well as probation violations.

Officials say Johnson was released on extended supervision from the Milwaukee Secure Detention Facility on Nov. 26. He had been living with the victim in the Town of Barton for several weeks prior to the alleged attack. 

Johnson was last known to be in the city of Milwaukee operating a stolen black 2002 Chevy Tahoe that at the time displayed a Wisconsin registration plate of UA7373.

Johnson is described as a Black male, 5'5", 215 lbs. with black hair and brown eyes.

The sheriff's office says Johnson is thought to be armed and dangerous. If you see Johnson, call 911 and do not approach him.
