Oakland Police Department Chief Howard Jordan justified the use for force by his officers in crackdown of the Occupy Oakland protests Tuesday, saying in a statement released Friday that "our officers used what they believed to be the least amount of force possible to protect themselves and gain control of the situation."

But he also said a thorough internal and external investigation would be done to address complaints about the excessive use of force against protestors.

Jordan's statement came after Oakland Mayor Jean Quan apologized about the violence, but was booed off the stage late Thursday before she could address the protestors.

Some protestors have called for a city-wide strike.
