Residents in the St Giles High Street area of central London have claimed there has been an influx of drug dealers and addicts into the area.
They said it follows a police operation in neighbouring Soho to clean up the area ahead of the Olympics.
Labour councillor for Holborn Sue Vincent said the gangs were "incredibly threatening".
Westminster police said it was working with officers in Camden in making the whole of the West End a safer place.
