Climate-change protesters gathered outside the headquarters of the British Broadcasting Corporation (BBC) on Thursday as part of protests seeking to demand more action to tackle global warming.
Protesters chanted "BBC, tell the truth", referencing their 'tell the truth' slogan - one of three primary demands the protesting Extinction Rebellion group has featured on its official website.
The group has blocked several locations in central London in recent days after it staged a protest in parliament earlier this month.
More than 500 people have been arrested this week and 10 charged so far, police said.
London's police force said it had cancelled some officers' leave and was calling in assistance from other forces to deal with protesters who were causing "unacceptable" disruption.
