A 54-pound sixth-grader is in police custody after he was was handcuffed and arrested at his Central Florida school for throwing sticks at a pregnant teacher and kicking another instructor.

Jason Stewart Lord was charged Thursday with battery on a pregnant woman and battery on a school official, both felonies. Palm Bay Police Department spokeswoman Yvonne Martinez says the 12-year-old was taken to a juvenile detention center where he was expected to stay overnight.

Martinez says the boy also punched the pregnant teacher last week but school officials decided to handle the matter internally at the time.
