A dye pack is a device used by banks to foil bank robbers non-violently. Bank robbery is the crime of robbing a bank. ...
Banks put dye packs in money given up during robberies. The dye pack is an incendiary device that explodes in a shower of colored ink, intended to permanently stain the stolen money and the robber's hands with a bright red color. Before the pack is used, it is stored next to a magnetic plate that keeps the pack dormant. When it is removed from the magnetic plate to be put into a money bag, it becomes armed. Within the pack is a small radio receiver that receives a signal sent by a transmitter at the door. This activates a timer that causes the pack to explode some short time later, such as when the criminal is in his getaway car. Incendiary refers to any fire that has been deliberately set. ...
