If it becomes apparent at some point before the suspect is processed by the custody officer that the arrested person will have no case to answer, owing to, perhaps, mistaken identity coming to light or it becoming apparent that no crime was committed or that the arrested person could not have been involved, the arrested person will be released before they are technically detained for questioning. It is this timing that makes the difference between being ‘de-arrested’ and ‘released without charge’.
S. 30 PACE sets out that de-arresting a suspect involves allowing ‘a person who has been arrested under any act of law at a place other than a police station …[to] be released before reaching a police station if a constable is satisfied that there are no grounds for keeping him under arrest’.
However, being de-arrested does not rule out the possibility of re-arrest, albeit on different charges. This was widely publicised in 2006, when
George Michael was arrested on suspicion of being unfit to drive when he was found dazed at the wheel of his car on a busy traffic junction. Moments after being de-arrested, the singer was
re-arrested on suspicion of possession of class C drugs after Cannabis was found in his car.
