Metropolitan Police officers will no longer be able to access TikTok and other social media sites as the force bans its use on work phones.
The UK's biggest police force, which employs around 30,000 officers, has become the latest major organisation to block access to the platform along with other social media apps with the exception of WhatsApp.
The move comes as part of a major smartphone upgrade being rolled out across the force and follows the announcement earlier this month that Parliament staff would also no longer be able to use the platform on professional devices.
Scotland Yard said staff would continue to be able use maps, news and transport apps, but not social media.
The rollout has already begun with selected teams given the new phones with tighter restrictions, the force said, but did not specify which or how many.
A Met spokesperson told the Mirror: "Met devices routinely issued to officers cannot access Tiktok.
"In recent years the Met has rolled out mobile phones to officers in various teams and restricted the use of certain applications including TikTok."
WhatsApp, the Met said, was not included in the list of blocked apps despite being officially a social media app, although using it could only be on a restricted basis and with express permission from managers.
News of the ban comes as the Casey Report published this month concluded the force was institutionally racist, sexist and homophobic.
Baroness Louise Casey, who underwent her investigation following the murder of Sarah Everard, found a "rotten" culture permeating throughout ranks, recommending the force make fundamental changes to root out its problems or be abolished.
Cabinet Office minister Oliver Dowden also announced this month that TikTok, which lets users scroll through videos on an algorithm tailored to their viewing history, would no longer be allowed on Government staff phones following the same move from various EU countries and the US Government.
Many senior officials have expressed concerns about use of the Chinese-owned app on Government phones due to fears about how it takes and stores users' data.
