Although five people were arrested on suspicion of public order offences, most of the demonstrators left Paternoster Square quickly and peacefully last night.
A group of anti-capitalist protesters had set up a temporary camp outside the London Stock Exchange - more than six months after Occupy London was prevented from taking over the square.
A spokesman for the campaign group said: "This was something we had wanted to do on October 15 and we have finally done it.
"This is a force that will not be stopped."
