Protester falls off police car at Black Lives Matter protest

The protesters gathered in Los Angeles, halting traffic on a freeway over the killing of an unarmed black man by a white police officer in Minneapolis earlier in the week.

Local media reported that the man was being treated and that his condition was unknown.

In Minneapolis, hundreds of protesters gathered on the second day on Wednesday, clashing with police in riot gear who fired tear gas into the crowds and lobbed concussion grenades.

Mayor Jacob Frey called on prosecutors to file criminal charges against a white police officer shown on a bystander's video pressing his knee into the neck of a handcuffed African-American man, identified as George Floyd, who later died at a hospital.
