A second Iraq War veteran was hospitalized Friday after officials said he was hurt during protests in Oakland a day earlier.

Kayvan Sabeghi, 32, was being treated at Oakland's Highland Hospital and was in fair condition, hospital spokesman Curt Olsen said, without releasing further details of Sabeghi's injuries, or of his treatment.

A week earlier, Marine veteran Scott Olsen, 24, suffered a skull fracture during clashes between police and Occupy Oakland participants in California on Oct. 25. Olsen, who also served in Iraq, worked his day job as a security software engineer and joined participants at night at Occupy San Francisco before traveling across the bay to the Oakland site where he was injured.

Dottie Guy, of the Iraq Veterans Against the War, said Friday that Sabeghi was in the intensive care unit of the hospital after suffering a lacerated spleen and internal bleeding. Guy said Sabeghi was taken to the hospital after being arrested and held in a jail cell.

Records show Sabeghi was booked early Thursday during the Occupy Oakland protests on suspicion of resisting arrest. He was one of 103 people officials said had been arrested by 3 p.m. Thursday.

Guy said when she spoke to Sabeghi early Friday he was in a "lot of pain."

Oakland police said they were conducting an investigation into the circumstances of his arrest, but would provide no additional details.

Guy said Sabeghi served with the Army in both Iraq and Afghanistan.
