  "Arrests for offences the Counter Terrorism Policing Headquarters considers terrorism-related, at the time of arrest or later in the investigation, under the Terrorism Act's section 41 and other legislation, by the quarter of arrest (the Home Office's notes 2 and 5). Recent figures can change as cases progress.",

  "People in custody are those held for terrorism and terrorism-connected offences, on remand or sentenced, at the end of each quarter (the Home Office's note 2); from the 30th of September 2020 the Home Office counts terrorism-connected offenders, so earlier figures are not comparable (its note 4).",
