WARREN, Ohio -  A Warren man has pleaded not guilty to charges filed after he allegedly fondled a woman who was shopping at a convenience store.

A 29-year-old woman told police she was buying pop at a store at West Market Street and Iowa Avenue Thursday night when a stranger walked up from behind and grabbed her buttocks.

When the woman yelled “Don’t touch me!”, she said the man laughed and told her she had a great body before touching her some more.

The woman says she hurried out of the store where her boyfriend and his daughter were waiting in a car.

When the boyfriend got out of the car, he said the suspect pulled a knife. The boyfriend told police he pulled out his own knife and the suspect ran away.

The couple flagged down a police officer and led him to Hamilton Street and Nevada Avenue where the officer spotted 37-year-old Joshua Wilson.

The officer said that he tried to remove a kitchen knife in Wilson’s pocket and struggled with the suspect until a second officer could arrive and help make the arrest.

Wilson was arraigned in municipal court on Friday, pleading not guilty to charges of sexual imposition, aggravated menacing, carrying a concealed weapon, and resisting arrest.

Another hearing for Wilson is set for November 16.
