Protesters have held a second day of demonstrations in London near the venue of the G20 summit and in the City.
Several hundred people gathered near the ExCel centre in docklands and around 400 outside the Bank of England.
Around 100 were caught in a stand-off with police outside the bank and there were some minor skirmishes when others were boxed in, but most were peaceful.
There have been 122 arrests related to the G20, including 86 on Wednesday and 32 on Thursday, police said.
World leaders held talks throughout the day at the ExCel centre, a few hundred yards from protesters.
There was room for about 6,000 but only a few hundred turned up, the BBC's Ben Brown reported.
He said the "noisy but calm" crowds were kept well away from the conference centre amid tight security.
Stop the War Coalition, the British Muslim Initiative, CND and Middle East campaigning groups were among the varied groups who took part.
Protesters were allowed in one area only, outside the security fence erected around the conference hall.
In the City, police officers corralled around 100 protesters on to the pedestrianised area in front of the Bank of England.
More were cleared from surrounding streets and there were minor clashes as other pockets of protesters were contained in small areas.
Many people had gathered outside the bank in support of a man who died in the protests on Wednesday evening.
Police confirmed the circumstances behind the death have been referred to the Independent Police Complaints Commission (IPCC).
Scotland Yard said he had collapsed near the Bank of England and was taken to hospital where he was pronounced dead.
City of London police named him as Ian Tomlinson, 47, and said he was on his way home from working at a newsagents at the time.
Meanwhile, police raided two squats in east London to arrest people they believed had links to Wednesday's protest violence.
Officers in riot gear questioned around 60 people at one squat in Earl Street near Liverpool Street Station, but police have not reported any arrests there.
The BBC's Dominic Hurst said a crowd of about 30 demonstrators chanted "shame on you" at police, but the situation remained peaceful.
Around 20 more were questioned at Rampart Street in Aldgate, where police say four people were arrested - two for violent disorder and two for possessing an offensive weapon.
On Thursday morning 40 protesters met outside the London Stock Exchange where they had threatened to disrupt business, but they were outnumbered by 100 police officers.
Elsewhere, campaigners got their message across in other ways.
A small number of protesters played a giant game of Monopoly in the City, armed with huge crates of fake money.
While French freeclimber Alain Robert, known as the Human Spider, scaled the Lloyds' building in the capital as part of protests. He unfurled a banner but returned to the ground.
An estimated 5,000 people took part in Wednesday's protests which were mainly peaceful and good-humoured but punctuated with violence.
Stuart Fraser, from the City of London Corporation, said Wednesday's security operation was a success.
"The high cost [of the security operation] is the price of democracy," he added.
Those arrested were held for offences including violent disorder, obstruction, aggravated burglary, arson and unlawful possession of police uniforms.
