> Data from the Crown Prosecution Service (CPS), obtained by The Telegraph under a Freedom of Information request, reveals that 292 people have been charged with communications offences under the new regime.

This includes 23 prosecutions for sending a “false communication”…

> The offence replaces a lesser-known provision in the Communications Act 2003, Section 127(2), which criminalised “false messages” that caused “needless anxiety”. Unlike its predecessor, however, the new offence carries a potential prison sentence of up to 51 weeks, a fine, or both – a significant increase on the previous six-month maximum sentence.…

> In one high-profile case, Dimitrie Stoica was jailed for three months for falsely claiming in a TikTok livestream that he was “running for his life” from rioters in Derby. Stoica, who had 700 followers, later admitted his claim was a joke, but was convicted under the Act and fined £154.
