UK arrests per day for online posts
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Reporting by The Times and parliamentary materials put UK arrests for certain online communications at about 12,000 in 2023 — roughly “more than 30 arrests a day” — a figure reproduced across media and parliamentary debate [1] [2] [3]. Government-published central data on these specific offences does not exist; the Times number was compiled from FOI responses and not all forces replied, so it is an estimate rather than an official national tally [4].
1. What the headline number actually is — and where it came from
The oft-repeated “more than 30 arrests a day” derives from The Times’ analysis of FOI responses and related reporting that tallied about 12,000 arrests for offences under section 1 of the Malicious Communications Act 1988 and section 127 of the Communications Act 2003 in 2023 [1] [2]. Parliamentary briefing confirms the government does not publish arrests by those specific offence codes centrally, and that the Times used data collated from individual forces — with some forces not providing figures — so the aggregate is a journalistic reconstruction, not a Home Office statistic [4].
2. Legal frame: what laws are being applied
The arrests cited are primarily for offences under the Malicious Communications Act 1988 and section 127 of the Communications Act 2003, which criminalise sending “grossly offensive”, indecent, obscene or menacing communications and similar conduct online or via other communications media [4]. Parliamentary debate and library briefings note the same statutory framework when discussing trends and free‑speech concerns [3] [4].
3. Trends and interpretation: arrests up, convictions down — why that matters
Multiple sources point to a rise in arrests since 2017 alongside a long-term fall in convictions and sentences for those offences, suggesting many arrests do not culminate in criminal punishments — prosecutors cite evidential difficulties or victims not supporting further action as common reasons [3] [4]. Critics say this pattern risks “setting an example” via arrest even when cases do not proceed, raising civil‑liberties alarms that policing priorities and chilling effects on speech deserve scrutiny [3].
4. What the numbers do and do not show about policing practice
The FOI‑based totals reflect recorded arrests under those statutes but do not on their own reveal motive, proportionality, context, or whether posts incited violence or hate; independent fact‑checking cautions that the headline counts are being shared “without context” and that the laws also cover threats, terrorism incitement and other harmful communications [5] [4]. BBC reporting on specific events (e.g., riots) shows police have also used arrest powers in response to violent or inciting online content, so some arrests relate to clear public‑safety concerns [6].
5. Political and media framing: competing narratives
Conservative commentators, civil‑liberties groups and some media outlets frame the figures as evidence of overreach and censorship; think tanks and MPs have described a “free speech emergency” [3]. Other reporting and official voices stress that arrests are responses to genuinely harmful online behaviour, and that the underlying laws were passed by Parliament — an argument invoked by ministers asking police to prioritise street crime over less serious posts [7] [6]. Both perspectives appear in the sources.
6. Data gaps and methodological caveats you should know
The Home Office does not publish arrests by the specific communications offence codes centrally; the Times’ total is compiled from FOIs and not all forces responded, and some later media tallies (e.g., Daily Mail/others) show different yearly totals depending on which forces cooperated [4] [8]. Independent debunking work warns headline claims (e.g., “more than 1,000 arrests a month”) are floated without context; similarly, partisan outlets sometimes present the totals as definitive national government statistics when they are not [5] [8].
7. Bottom line and what to watch next
Current reporting supports the claim that arrests for online communications offences climbed into the low‑to‑mid tens of thousands annually in recent years and are commonly summarized as “about 12,000 in 2023” or “more than 30 a day,” but that total is an FOI‑based journalistic estimate rather than a single government release [1] [2] [4]. Watch for (a) any Home Office publication breaking down arrests by specific offence codes, (b) follow‑up FOI releases from police forces that fill gaps in earlier compilations, and (c) parliamentary or ministerial responses promising law review or data transparency — all of which sources say are central to the debate [4] [3] [7].
