A man has been arrested on suspicion of violent disorder after a crowd gathered at the Indian High Commission in London.
Windows were smashed and two security guards were injured at the building in Aldwych, Westminster, at around 1.50pm.
Footage posted on social media shows a man detach the Indian flag from the first-floor balcony of the building.
A number of people below waving bright yellow ‘Khalistan’ banners appear to encourage him.
They are believed to be supporters of a Sikh separatist movement seeking to create a new homeland or breakaway state.
It comes as mobile internet services in the Indian state of Punjab are suspended until Monday while police pursue the leader of a Sikh separatist movement.
An investigation into the incident at the Indian High Commission has been launched by the Metropolitan Police, as politicians speak out to condemn the violence.
