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.
