Advice for investigative officers

This section relates to till cash protection security systems used in financial institutions and retail outlets.

What to ask staff:

  • Was a security pack taken or handed to the raider?
  • Was the security pack in a bag or in a pocket?
  • What type of bag was used?
  • After what delay was the security pack designed to activate (usually 10 seconds)?

Escape on foot:

  • Establish all the alternative locations where the security pack would be 5 to 10 seconds after activation, when the smoke reaches its’ full emission rate.
  • This could be 15 to 20 seconds from the premises, taking into account the delayed activation.

What to look for:

  • The complete discarded bag, with contents.
  • The security pack and some scattered banknotes, polythene bags may melt.
  • Discarded stained clothing.

 Where to look (immediately following the raid):

  • Behind walls, hedges and fences.
  • Temporary hiding places.

Escape by car:

  • Placed on a seat, the security pack will progressively fill the vehicle with red smoke.


  • Security packs produce a cloud of red smoke for about 20 seconds drawing attention to it, the raider and vehicle used.
  • It is important to identify/appeal for witnesses who may have seen the red smoke as they may hold valuable eyewitness evidence.


  • Following an activation of a security pack, stains on money, clothing, vehicles, etc., may help identify the suspect.
  • In some cases the stain may contain a unique identifier.
  • Controlled samples of the dye are available on request.
  • There are a number of other identity checks that can be made and officers should contact Banknote Watch for this information.
