More than 100 arrested in Oakland 'riots'

Protests erupted on the streets of Oakland Wednesday night after a young man killed by a subway police officer was laid to rest, CNN reported.

Twenty two-year-old Oscar Grant was shot and killed on New Year's Day in a crowded BART train station by 27-year-old Officer Johannes Mehserle.

Mehserle is accused of shooting Grant while he was lying face-down on the station platform. Grant's death prompted demonstrators to take to the streets Wednesday night, and more than 100 people were arrested by police, according to KCBS-TV.

Officer Mehserle reportedly resigned from his post, which has hampered the police department's internal investigation because he can no longer be compelled to provide a statement to the department's investigators, KCBS reported.

Some protesters carried signs reading "Jail Killer Cops," while others (including some shown in the YouTube video below) angrily confronted Mayor Ron Dellums.

Some demonstrators chanted "No justice, no peace, f*** the police!" and "Pigs go home!," as shown in one of the videos below.

"People have lost confidence in the process of the investigation," Dellums acknowledged. He said he had directed the Oakland Police Chief to investigate the homicide and not to treat the case any differently because a police officer is suspected.

Dellums also called on protesters not to use violence to respond to violence. "Screaming and yelling and burning and harming human beings is not what we should be all about," he said. "I've given my whole life to the notion that peace is a superior idea."
