For the answer to the question above,
Well, I believe the answer on your question is 3 parts.
1. Part A is attached to the detainee in order to restrict detainee's movement, could be made from any type of durable material.
2. The Part B is retained by the capturing unit and maintained in the unit's records lastly.
3. The Part C is attached to the tools/belongings confiscated from the detainee, so it could be matched later.
