Police arrest 140 revellers on day one of Notting Hill Carnival

A total of 140 people have already been arrested on the first day of Notting Hill Carnival for offences including assaults on police, robbery and possession of weapons. That is 40 per cent more than the number arrested on the opening day of the world-famous street party in west London last year, when 104 were detained. It comes as the Met Police has vowed to crack down on crime at the event, deploying knife arches and live facial recognition cameras to locate people on watchlists.
