Christine Jones, Metropolitan police commander, praises "dedication and bravery" of police officers in dealing with the "challenging" disorder:
"This is a challenging situation with small pockets of violence, looting and disorder breaking out on a number of boroughs.
"We have deployed units across London and continue to move quickly to deal with any reports of criminality as soon as possible.
"Officers are once again putting themselves in harm's way to arrest those responsible and prevent further crimes. I am proud of their dedication and bravery.
"I, along with the vast majority of Londoners, condemn this mindless criminality. It serves no purpose and only results in the destruction people's livelihoods and communities."
