More than 3,000 suspected rioters have been arrested by police investigating the disturbances across London in August.
Detectives from Operation Withern continue to examine evidence of crimes committed during the riots and 1,931 people have now been charged or cautioned.
The investigation has so far led to 1,809 people being brought before the courts, with 618 sentenced and 255 jailed. Some 1,058 cases are still ongoing.
Commander Steve Rodhouse, who is in charge of the investigation, said the total number of arrests was 3,003.
"This is an important milestone for the investigation but our work is far from over," he said.
"We continue to arrest and charge people every day, which is testament to the hard work of the officers involved in this investigation.
"It is also important that the public see we are not only arresting people but that these arrests are ending up with people being convicted for their crimes."
He added that those involved in the riots would "not get away with it" and said there would be more arrests and convictions.
