Getting Hurt

it's only been two days since the school year began and my lil guy came home with these. The new teacher must have held him too much for her fingers to have marked on both of his arms. :( I saw a picture where they put in his clothes in the chair maybe so he can't run away. And it has caused him bruises at the back. I'm so sad for my little boy. It's so painful for parents to see this.  I wish he can talk so he can tell the person so not hurt him. So he can tell me who hurt him. :(
