Police considering plastic bullets
Plastic bullets are being considered by police chiefs as a tactic to bring the unprecedented rioting in London under control.
Deputy Assistant Commissioner Stephen Kavanagh said Scotland Yard was "not going to throw 180 years of policing with the community away" as the prospect of using the ammunition for the first time at a British disturbance was raised.
"The use of any tactics will be considered carefully," he said. "That does not mean we are scared of using any tactic."
There are now 30 outside forces helping Scotland Yard to deal with the riots, according to a spokeswoman for the Association of Chief Police Officers.
Meanwhile, CCTV images capturing people police want to speak to in connection with the riots have been released by Scotland Yard.
Detectives leading the operation against the wave of disorder across London vowed to bring those caught on camera who were proven guilty of crimes to justice.
Images showed some young men and women did not even bother to hide their identities as they allegedly looted areas of Croydon and Lambeth. Others appear menacing with their hoods pulled up and masks over their faces.
Commander Simon Foy said: "As well as the many arrests and charges, the team is working hard to identify suspects."
Later it emerged that a total of 111 officers and five police dogs have so far been injured during the escalating riots.
Deputy Assistant Commissioner Kavanagh said: "The level of violence directed against our officers as they have bravely done their duty to keep London safe is unprecedented."
