PROTESTS continued to swell in Sacramento today over the police killing of unarmed black man Stephon Clark last week.

California’s attorney general Xavier Becerra will join an investigation into the death of Mr Clark, who was in his grandmother’s back garden when police shot him 20 times.

A city council meeting yesterday night had to be called to a halt early after crowds filled the hall to overflowing and Mr Clark’s brother Stevante jumped on the dais in front of the mayor, chanting his brother’s name.
