An argument sent one teen to the hospital and another to jail after a stabbing at a school.

A 13-year-old was stabbed in the stomach at Hickory Grove Elementary School in the 6700 block of Pence Road around 7 p.m. Tuesday. He was taken to the hospital with serious, but non life-threatening, injuries, police said.

Officers said the two teens knew each other and the stabbing was the result of an earlier argument.

The older teen is in custody.

The stabbing may be gang related, police said.
