Protester placed lock around his neck on M25 gantry near London Colney

Hertfordshire police said they were made aware of a person on the gantry at junction 22, near London Colney, at around 7am.

They found he had secured himself with "both a harness and a D-lock". The lock "had been placed around his neck and locked on to the cables that run along the structure".

Police added that they have put additional measures in place so “legitimate media can do their job”, after reports of journalists being held in custody for hours.

They accepted that “in retrospect” the arrest of LBC journalist Charlotte Lynch “would not have been necessary”.
