London transport staff warned of razors inside Covid conspiracy posters

"Staff on London’s public transport network have been warned that blades are being concealed inside posters promoting conspiracy theories about Covid-19 and vaccinations.

Transport for London (TfL) said there had been a number of reports of razor blades being attached to the back of the posters intended to harm anyone taking them down, and that at least one person was harmed in an incident outside its network."
