Hong Kong police were called in to respond to a rusting firearm found by workers doing some weed clearing near a flyover. They were unable to initially determine if the firearm was an imitation or a real one so it got sent to the lab for identifucation. The firearm was inside a canvas bag but was covered with weed when found. The firearm seems to be there for less than a year ago, as previously there was none found when a weed clearing was done last year.
