Late Wednesday afternoon, reports surfaced that the man had been identified as Scott Thomas Olsen, of Onalaska, Wis., a 24-year-old Marine Corps corporal and Iraqi war veteran. He reportedly remains critical condition at Highland Hospital, where he is being treated for head wounds and brain swelling. (Watch the video below, which shows a disturbing, chaotic scene filled with tear gas and features some NSFW profanity.)

More than 100 people were arrested in Oakland. The city's police chief Howard Jordan defended his decision to use tear gas against the protestors: "We were in a position where we had to deploy gas in order to stop the crowd and people from pelting us with bottles and rocks," he told the Los Angeles Times.

Protesters were throwing paint "and other agents" at officers, Jordan added of the crowd, which reached about 1,000 people.

"The crowd started throwing bottles, paints, beer, eggs at myself and the other officers," Officer David Carman told KTVU-TV Channel 2.

Police are wearing riot gear Wednesday morning.
