Thousands marched in 27 cities around the US last Sunday in solidarity with Occupy Oakland in California.
On Saturday Oakland protesters attempted to occupy a building that had been vacant for six years.
They planned to use it as an organising hub and a community centre providing free education, housing and healthcare services to the 99 percent.
But they were met by hundreds of armed police, who used teargas, rubber bullets and baton rounds to evict them.
Police arrested over 400 people.
Within 24 hours solidarity marches were building in New York and other cities where Occupy protests have taken place.
The day of action for Oakland follows protests last week outside banks in San Fransisco’s financial district.
Over 1,000 people took part in them.
The Occupy camps may no longer be in place. But the movement has given new life to the struggles against student debt and home foreclosures.
