BENTON TOWNSHIP, Mich.  —  Authorities in Michigan say a hunter's stray bullet has grazed two young boys at a day care near Cheboygan.

The Cheboygan County sheriff's department says a 43-year-old woman fired her rifle at a deer on Thursday but the bullet penetrated a wall and grazed the boys — ages 3 and 5 — inside Angie's Country Kids Day Care in Benton Township.

The Petoskey-News Review reports they were released from a hospital after treatment.

Authorities say the woman was hunting about 400 yards away, and may not have realized there was a day care in the area.

The county prosecutor's office is expected to review the case.
