Police say surveillance video of the June 30 attack shows 23-year-old Oakland resident Christopher Porter-Bailey kick the woman in the face while she is on the ground, seemingly for no reason.
The woman had been robbed of her purse and cellphone by a group of suspects that allegedly included Porter-Bailey, and the kick to the head knocked her unconscious.
Police announced Porter-Bailey’s arrest on Wednesday. He was taken into custody last week and has been charged with robbery, aggravated assault and battery likely to produce serious injury.
It was not immediately clear whether he had an attorney.
At least three other people have been arrested in connection with the attack.
