An Albert Lea man was found guilty of interfering with privacy — window peeping — during a court trial Tuesday.

Matthew Alan Radke, 37, was sentenced Wednesday in Freeborn County District Court by Judge Ross Leuning after he was found guilty of the gross misdemeanor act. Radke was convicted of sexually abusing a young child in 2008, for which he was on probation and a 21-month jail sentence was stayed.

Radke was sent to prison for the 21-month sentence, but will get credit for his time in custody. Radke admitted to his probation agent that he had been window peeping, and the agent reported it to local police who arrested Radke for probation violation.

Court documents state the agent and a detective with the Albert Lea Police Department interviewed Radke Nov. 22, during which time Radke reportedly admitted to looking in the window of a house and watching a young woman changing clothes on Nov. 18.

He reportedly stated he returned to the window at least three times until he saw that the girl was fully dressed.

Radke was convicted in 2008 of second-degree criminal sexual assault of a child younger than 16. He is on probation for 20 years.

Included in his probation conditions are rules to attend a sex offender program, to register as a predatory offender, to have no contact with people under 18, to not possess any sexually explicit material and to not access the Internet without prior approval, among others.
