A 10-year-old boy is recovering after a pit bull attack left him with injuries so severe that he had to have his arm amputated.

The boy was alone at his Paw Paw home in Van Buren County, Michigan, for a short time this weekend.

Investigators say that is when the family's two-year-old pit bull attacked the boy.

When the boy's older brother returned home, he was able to free the victim and rush him to the hospital.

The boy, whose name has not yet been released, is now being treated at a hospital in Kalamazoo.

Neighbors say this dog bit someone else earlier this year.

Police say the dog has been euthanized.
