Up to 100 people have been arrested on suspicion of "hate crimes" in dawn raids across London.

Scotland Yard said between 80 and 100 people suspected of racist, homophobic or domestic violence offences were detained in swoops on a dozen addresses.

More arrests are expected.

Alleged offences include racially aggravated death threats, harassment, the publication of racist or homophobic material, and assault.

Robust

"Hate crime will not be tolerated in London," said Detective Chief Superintendent John Godsave.

"Today's arrests are another example of the Met's commitment to show that hate crime will be robustly dealt with."

Earlier this month the Metropolitan Police launched a campaign against hate crimes.

As well as distributing leaflets and posters, officers have visited schools to discuss hate crimes with pupils.

Bollywood cinemas in campaign

A cinema campaign is also running urging young Londoners in particular to report hate crime.

The month-long promotion dubbed March Against Hate will screen alongside films such as Proof of Life, The Gift and The Watcher.

It is running in 300 cinemas including those specialising in Bollywood films.
