Breaking News: Baby attacks me on BART train!

As I was hurrying to get to work this morning a baby attacked me and tried to prevent me from getting off the BART train. It reached out with it's little rat-claw and grabbed hold of my arm. I nearly yanked it from it's mother's grasp. It screamed and refused to let go. I blocked the door with my foot to prevent the train from leaving.
"Let go of me!" I shouted.
The demon child screamed back at me, refusing to let me free! It had long nails for an infant and they dug into my arm.
"I will strike your child!" I screamed at the mother.
She finally coaxed her evil spawn into relasing it's grasp and gave me a look that said "He's only a child!".
I don't care how old he is. Assault is assault at any age.
