Known as "the Mosquito", the device is a popular youth-deterrent in the UK, where shop keepers have used it to keep kids away from strorefronts.
"The Mosquito, as the $1,000 device is called, hung outside the Chinatown entrance to the Gallery Place Metro station Tuesday, annoying its intended targets and then some. The young and a few not-so-young could hear the piercing, constant beeeeep, beeeeep, beeeeep.
'I can definitely hear it very loudly,' 19-year-old Brooke Sawinski said. 'It's pretty blasting.'"
