COVID-19: Anti-vaccine posters found with razor blades attached to cut people who take them down, union says

Transport for London (TFL) workers have been warned about taking down unofficial COVID posters, after a union confirmed anti-vax signs have been found with razor blades attached to the back of them. The Rail, Maritime and Transport (RMT) union said the posters had been put up on rail and tube stations in London. The union has called for action to be taken against those responsible for the posters, which bear the message 'Masks Don't Work' and have a razor blade attached on the rear - potentially injuring anyone who tries to take it down.
