Note 4C from PACE 1984 Code D:
4C The power under section 61(6A) of PACE described in paragraph 4.3(e) allows fingerprints of a suspect who has not been arrested to be taken in connection with any offence (whether recordable or not) using a mobile device and then checked on the street against the database containing the national fingerprint collection. Fingerprints taken under this power cannot be retained after they have been checked. The results may make an arrest for the suspected offence based on the name condition unnecessary (See Code G paragraph 2.9(a)) and enable the offence to be disposed of without arrest, for example, by summons/charging by post, penalty notice or words of advice. If arrest for a non-recordable offence is necessary for any other reasons, this power may also be exercised at the station. Before the power is exercised, the officer should:
• inform the person of the nature of the suspected offence and why they are suspected of committing it.
• give them a reasonable opportunity to establish their real name before deciding that their name is unknown and cannot be readily ascertained or that there are reasonable grounds to doubt that a name they have given is their real name.
• as applicable, inform the person of the reason why their name is not know and cannot be readily ascertained or of the grounds for doubting that a name they have given is their real name, including, for example, the reason why a particular document the person has produced to verify their real name, is not sufficient.
