Criminals in Hong Kong have plumbed new depths amid the coronavirus outbreak and the associated panic-buying. Police say three masked men armed with knives threatened a deliveryman before stealing around 600 rolls of toilet paper from outside a supermarket early Monday, the South China Morning Post reports. Shortages—and rumors of impending shortages—have caused people to stock up on items including toilet paper, face masks, and hand sanitizers, as well as staples like rice and pasta. Police say two suspects were arrested later Monday and some of the stolen toilet paper was recovered, the BBC reports. "This is a senseless act and we are shocked," says a spokesperson for the Wellcome supermarket chain. (More Hong Kong stories.)
