Bibb County campus police arrested three people Monday who were on school property at Ingram-Pye Elementary School.

School system spokeswoman Stephanie Hartley said a “code red” was issued for the school at 3:40 p.m., when children were being picked up after school. The lockdown lasted for about 10 minutes, Hartley said.

Hartley said she wasn’t told what the charges were or who was arrested.

The school system plans to send automated phone calls to parents Monday and Tuesday to inform them of the situation.
