Morrow High School is operating on a normal schedule after being placed on lockdown late on Wednesday morning.
Police were searching the immediate area for some suspects that may be linked to break ins at some homes in a nearby neighborhood. Clayton County Sheriff Victor Hill says one burglary suspect is in custody, and police are searching for a second suspect.
Hill says the school was on lockdown as a precaution.
School officials say the lockdown was lifted around 11:30 a.m.
