HANCOCK, Md. (WUSA9) -- Officials in Maryland say they had to use mace to subdue a "larger than normal" 6-year-old boy who had stabbed his grandmother.

It happened at 8:35 a.m. Monday in the 13700 block of Orchard Ridge Road in Hancock, Md., where deputies were called for a report of "an out of control 6-year-old" who had stabbed his grandmother and was attempting to stab his mother as well.

Deputies entered the home upon arrival and found the boy, who weighed approximately 100 pounds and charged the deputies wielding a large butcher-type knife in each hand, officials say. As the boy charged, he was waving both knives in a stabbing motion.

One shot of pepper spray was sprayed at the child which caused him to drop the knives and fall to the ground, officials say. The child was then taken into custody without further incident and transported to the Mertitus Medical Center for a mental evaluation. No criminal charges are being filed at this time due to the age of the child.

The child was not harmed as a result of the pepper spray. No deputies were injured.

The child's grandmother did suffer a laceration on her hand but refused medical treatment.
