Three Extinction Rebellion activists held after Thames rig protest

Protesters demanded London mayor Sadiq Khan cancel Silvertown road tunnel project

Three Extinction Rebellion activists were arrested and taken into custody after locking themselves to a rig in the middle of the Thames to protest against a planned road tunnel underneath the river in south-east London.

The keys to the locks around the protesters' necks were delivered to the capital's mayor, Sadiq Khan, with a note asking him to come and talk to them. However, the mayor's office issued a statement ignoring the request and confirming plans to build the Silvertown tunnel are continuing.
