Police in Sioux Falls, South Dakota say a 17-year-old boy has been arrested after he shot his mother in the back with a homemade arrow fired from a makeshift bow.

Police spokesman Sam Clemens say the two got into an argument Tuesday evening.

Clemens says the boy used a fishing pole and a shoelace to make a rudimentary bow, then fashioned an arrow out of a sharpened plastic rod.

He says the mother ended up with a small cut on her back.

Police took the boy to a juvenile detention center.
