The weather’s getting hotter and the skirts are getting shorter – and it seems the perverts are out in force. Right on the heels of a laowai pervert and a wet nurse sex ring, CCTV is now reporting that Chaoyang District police have arrested 15 people who are part of a ring that uses cameras concealed in walking sticks and other devices to take very low-angle videos of women in short skirts in various public areas and changing rooms in Chaoyang District.
