(CNN) -- A 7-year-old first-grader showed up at school Monday with two loaded handguns, Baltimore County, Maryland, police told CNN Tuesday.
One of the guns was discovered about 10:15 a.m. when it fell out of the student's pocket at Randallstown Elementary School, just outside of Baltimore, police said. The teacher immediately took the student to the office and police were called.
After police arrived, they searched the child's locker and found another loaded handgun in a book bag, Baltimore Police Cpl. Mike Hill said.
He said police believe the 7-year-old stayed at an uncle's house in Baltimore over the weekend, and found the guns there. Police believe he thought they were toys, he said.
"We don't believe the child had any idea that he still had the guns or do we believe he had any intentions to use the guns in a harmful way," Hill told CNN in a phone interview. Police believe the child got onto the school bus with both guns in his book bag and later discovered the weapons while he was at school.
Police would not comment on what kind of guns they were.
No charges will be filed against the 7-year-old, Hill said, but the uncle could face charges of child endangerment and leaving guns within reach of a child.
School officials called it a very unusual occurrence and would not comment on the status of the first-grader. Bringing a weapon to school carries a mandatory punishment of expulsion, according to Baltimore County Public Schools policy. E-mail to a friend
