A total of 890 arrests were made at a demonstration against the banning of Palestine Action as a terrorist group in central London on Saturday.
Police arrested 857 people under the Terrorism Act for showing support for a proscribed group, while 33 people were arrested for other offences, including 17 for assaults on police officers, the Metropolitan police said.
The force said those arrested were processed at a prisoner reception point in the Westminster area and those whose details could be confirmed were released on bail to appear at a police station at a future date.
Those who refused to provide their details, or were found to have been arrested while already on bail, were taken to custody suites.
The 857 people arrested under the Terrorism Act will be investigated by the Met’s counter-terrorism command.
