Occupy Oakland held their "Move In Day" demonstration on Saturday in Oakland, California.

Occupy demonstrators had hoped to occupy a long-time vacant convention centre, leading to hundreds of arrests and the Oakland police department's deployment of chemical weapons, rubber bullets and flash grenades on demonstrations well into the night.

Activists were deluged with tear gas during the day and kettled into mass arrests in the evening. At one point during the evening, activists broke into Oakland City Hall, damaging displays and burning an American flag.

A second Iraq veteran involved in Occupy Oakland demonstrations has been seriously injured, just over a week since Iraq war veteran Scott Olsen was seriously injured.

U.S. Army veteran (Iraq and Afghanistan), Kayvan Sabehgi, suffered a lacerated spleen from an alleged beating at the hands of Oakland police officers while attending a Occupy Oakland demonstration and general strike on Wednesday, November 2, 2011.

Sabehgi also claims that although he was in agonizing pain, he was forced to wait 18 hours until receiving proper medical attention at a local hospital.

Note: Occupy Toronto is having a march in solidarity with Oakland's general strike on Wednesday, November 2, 2011. Meet at St. James Park (King Street and Jarvis Street) at 4:00 p.m.

The first Occupy demonstration occurred in New York -- Occupy Wall Street -- on September 17, 2011. 

Iraq vet and former U.S. Marine Scott Olsen was struck in the head or shot by a police projectile on October 25, 2011, while attending an Occupy Oakland demonstration. Whatever weapon he was struck with, it fractured his skull leading to dangerous swelling of the brain.
