An Oklahoma man was arrested yesterday for allegedly masturbating in the women’s bathroom at a Tulsa Walmart, a solo act that was interrupted by a female shopper who discovered the naked suspect around 8:30 AM, police report.

Customer Beth Davis told police that she entered the restroom yesterday morning and found a nude man pleasuring himself in front of the mirror. Davis, who fled the bathroom in search of help, said that she later saw the suspect--now dressed--depart the bathroom and head for the Walmart’s exit.

So the 61-year-old Davis--who told TSG she was “in panic mode”--began filming him with her cell phone, while providing accompanying narration: “My name is Beth Davis and I witnessed it. You were naked and had your pants down around your ankles. Someone stop him. Do not let him go out that door.”

Davis’s 22-second clip, which she provided to TSG, can be viewed above.

While the man ran from the store, a second shopper photographed his vehicle and its license plate. Within two hours, Tulsa cops arrested Brian Hounslow, 37, for felony indecent exposure. Hounslow, seen in the above mug shot, was booked into the county jail, where he is being held in lieu of $5000 bond.

According to a booking report, Hounslow confessed to sex crime detectives that he had been masturbating in the Walmart bathroom. The document also notes that Davis saw Hounslow’s “fully exposed turgid penis.”

Pictured above, Davis, a grandmother of eight, said that Hounslow offered an apology, of sorts, when she confronted him after he left the restroom. Hounslow, she recalled, said, “I didn’t know it was the women’s bathroom.”
