Protesters descended on an open house at the former Olympic Village — now a condo development with units for sale — forcing police to shut down the event.

Picketers were angry that the development is offering fewer social housing units than planned.

Initially, the development was meant to be one-third social housing, one-third affordable housing and one-third market housing.

In April, Mayor Gregor Robertson cut the number of social housing units in half in an attempt to recoup the city’s investment in the project.

Some units will be rented at market rate and reserved for civic workers and low-income residents.

On Saturday morning, thousands of people showed up to look at some of the 475 condo units that went on the market that day.

The party ended when the protesters arrived.
