Brazil police say at least 1,000 people are building shacks on land they've occupied near the stadium that will host the World Cup's June 12 opening match.
Sgt. Artur Paz of the Sao Paulo police department says the land is less than four kilometers (two miles) from Sao Paulo's Itaquerao Stadium.
Paz says the Saturday morning occupation was peaceful and evictions are not planned for now.
He says he doesn't know why the Homeless Workers Movement undertook the occupation. The movement claims that around 1,000 families, rather than about 1,000 people, occupied the land.
The movement says on its website that more than 1 billion reals ($500 million) have been spent to build the stadium while thousands of people don't have a place to live, nor money to pay rent.
