Violent masked men have hijacked a peaceful protest outside a migrant hotel in which women in pink danced a conga.

Anti-immigrant and anti-racism demonstrators have held rival protests in London outside a hotel housing asylum-seekers.

Officers have been captured on video moving quickly in response to an escalation of the demonstration outside Britannia Hotel in Canary Wharf today - appearing to make at least one arrest after a group of masked men joined dozens of women and children gathered outside the building, which is reportedly being used as asylum seeker accommodation.
