The glove suitable for use at crime scenes comprises a unitary disposable glove with an outer surface having thereon machine readable indication enabling a glove bearing such an indication to be distinguished from a glove not bearing such an indication, such indication being provided on at least a palm portion and grip portions of the tips of four fingers and a thumb of the glove. The gloves are useful in a method of investigating a crime scene, wherein crime scene operatives don the gloves for handling items at the crime scene, and items at the crime scene are then machine read to identify prints thereon made by gloves of the crime scene operatives.
