The manager of an Arby's in Vancouver, Washington has admitted to urinating in customers' milkshakes on at least two occasions, police say. Stephen Sharp made the confession after he was taken into custody last week on suspicion of child porn possession and distribution, according to the Vancouver P.D. Following Sharp's revelation, investigators searched his cell phone and found a video that shows the fast food manager peeing in the mix used to fill the restaurant's milkshake machine, police say. Investigators also found child porn on his phone, they say. Another manager at the Vancouver Arby's says the restaurant served somewhere between 30 and 40 shakes and one ice cream float from the batch shown in the video. Police are now looking for anyone who purchased a milkshake from that Arby's on October 30th or 31st. As for Sharp, he's being held on $40,000 bail and is facing a laundry list of charges.
