Maumelle police officers spent the day at the school to calm any anxieties.
On Tuesday, police arrested James Austin for having a weapon on campus.
School leaders contacted parents by phone and email to keep them updated on what took place.
But they said they don't have every parent's contact information to alert them in emergencies."Make sure we have accurate information to reach you via telephone or email so we can contact you. Today we switch our telephone numbers so often and parents forget to give us current information," said Deb Roush, spokeswoman for the Pulaski County Special School District.
James Austin has to serve 30 days for violating his probation. He is currently in jail on a 40-thousand dollar bond
Investigators said they have no indication that he planned to harm anyone.
